Rule Not Applicable to FITF Applications
Note:
This rule does not apply to applications subject to the first inventor to file (FITF) provisions of the AIA.

[Editor Note: This MPEP section is not applicable to applications subject to examination under the first inventor to file (FITF) provisions of the AIA as set forth in 35 U.S.C. 100 (note). See MPEP § 2159 et seq. to determine whether an application is subject to examination under the FITF provisions, and MPEP § 2150 et seq. for examination of applications subject to those provisions. See MPEP §§ 717.02 et seq., 2154.02(c) and 2156 for the examination of applications subject to the first inventor to file provisions of the AIA involving, inter alia, commonly owned subject matter or a joint research agreement.]

Reference Must Be Co-Owned by Same Entities as Application
Note:
A reference can be disqualified as prior art if it was not co-owned by the same entities that owned the application at the time of invention.

Specifically, if an invention claimed in an application is owned by more than one entity and those entities seek to disqualify the use of a reference as prior art under pre-AIA 35 U.S.C. 103(c), then the reference must be owned by, or subject to an obligation of assignment to, the same entities that owned the application, at the time the later invention was made. For example, assume Company A owns twenty percent of patent Application X and Company B owns eighty percent of patent Application X at the time the invention of Application X was made. In addition, assume that Companies A and B seek to disqualify Reference Z as prior art under pre-AIA 35 U.S.C. 103(c). Reference Z must have been co-owned, or have been under an obligation of assignment to both companies, on the date the invention was made in order for the disqualification to be properly requested. A statement such as “Application X and Patent Z were, at the time the invention of Application X was made, jointly owned by Companies A and B” would be sufficient to establish common ownership.

Reference Must Be Jointly Owned by Same Entities
Note:
A reference can be disqualified as prior art if it was jointly owned by the same entities that owned the application at the time of invention.

Specifically, if an invention claimed in an application is owned by more than one entity and those entities seek to disqualify the use of a reference as prior art under pre-AIA 35 U.S.C. 103(c), then the reference must be owned by, or subject to an obligation of assignment to, the same entities that owned the application, at the time the later invention was made.

Requirement for Joint Venture Ownership of Application and Reference
Note:
Both the application and reference must be owned by, or subject to an obligation of assignment to, the joint venture at the time the invention was made.

For applications owned by a joint venture of two or more entities, both the application and the reference must have been owned by, or subject to an obligation of assignment to, the joint venture at the time the invention was made. For example, if Company A and Company B formed a joint venture, Company C, both Application X and Reference Z must have been owned by, or subject to an obligation of assignment to, Company C at the time the invention was made in order for Reference Z to be properly disqualified as prior art under pre-AIA 35 U.S.C. 103(c). If Company A by itself owned Reference Z at the time the invention of Application X was made and Application X was owned by Company C on the date the invention was made, then disqualification of Reference Z as prior art under pre-AIA 35 U.S.C. 103(c) would not be proper.

Moral Obligation Not Basis for Common Ownership
Note:
A moral or unenforceable obligation cannot establish common ownership of an invention.

The question of whether common ownership exists at the time the claimed invention was made is to be determined on the facts of the particular case in question. Actual ownership of the subject matter and the claimed invention by the same individual(s) or organization(s) or a legal obligation to assign both the subject matter and the claimed invention to the same individual(s) or organization(s)/business entity(ies) must be in existence at the time the claimed invention was made in order for the subject matter to be disqualified as prior art. A moral or unenforceable obligation would not provide the basis for common ownership.

Nonstatutory Double Patenting Rejections Authorized
Note:
The practice of rejecting claims based on nonstatutory double patenting in commonly owned applications is judicially authorized and can be overcome by filing terminal disclaimers.

In view of pre-AIA 35 U.S.C. 103(c), the Director has reinstituted in appropriate circumstances the practice of rejecting claims in commonly owned applications of different inventive entities on the grounds of nonstatutory double patenting. Such rejections can be overcome in appropriate circumstances by the filing of terminal disclaimers. This practice has been judicially authorized. See In re Bowers, 359 F.2d 886, 149 USPQ 57 (CCPA 1966). The use of nonstatutory double patenting rejections which then could be overcome by terminal disclaimers precludes patent protection from being improperly extended while still permitting inventors and their assignees to obtain the legitimate benefits from their contributions. See also MPEP §§ 804 and 1490, subsection VI.

Requirement for Common Ownership Disclosure
Note:
Patent application must disclose common ownership if inventions are related, as required by pre-AIA 35 U.S.C. 103(c).

Answer: Yes- If the required submission of common ownership is made of record in the patent application file. If invention #1 was invented by employees of Company A not working for Company C and Company A maintained sole ownership of invention #1 at the time invention #2 was made, inventions #1 and #2 would not be commonly owned as required by pre-AIA 35 U.S.C. 103(c).

Note:
The examiner may explain doubts about the accuracy of applicant’s representation of common ownership or assignment obligation and require objective evidence if such doubts arise.

In rare instances, the examiner may have independent evidence that raises a material doubt as to the accuracy of applicant’s representation of either (1) the common ownership of, or (2) the existence of an obligation to commonly assign, the application being examined and the applied U.S. patent or U.S. patent application publication reference. In such cases, the examiner may explain why the accuracy of the representation is doubted. The examiner may also require objective evidence of common ownership of, or the existence of an obligation to assign, the application being examined and the applied reference as of the date of invention of the application being examined. Examiners should note that the execution dates in assignment documents may not reflect the date a party was under an obligation to assign the claimed invention.

Company A and University B's joint research agreement allows Company A to invoke provisions of pre-AIA 35 U.S.C. 103(c) to disqualify University B’s application as prior art.

Company A and University B have a joint research agreement (JRA) in place prior to the date Company A’s invention X' was made. Professor BB from University B communicates invention X to Company A. On November 12, 2004, University B filed a patent application on invention X. On December 13, 2004, Company A filed a patent application disclosing and claiming invention X', which is an obvious variant of invention X. Invention X' was made as a result of the activities undertaken within the scope of the JRA. University B retains ownership of invention X and Company A retains ownership of invention X', without any obligation to assign the inventions to a common owner. Company A could invoke the joint research agreement provisions of pre-AIA 35 U.S.C. 103(c) to disqualify University B’s application as prior art in a rejection under pre-AIA 35 U.S.C. 103(a).

Requirement for Common Ownership or Joint Research Agreement Under Pre-AIA 35 U.S.C. 103(c)
Note:
The claimed invention and prior art must be commonly owned or subject to a joint research agreement at the time of invention to qualify as disqualified pre-AIA prior art.

In order to be disqualified as prior art under pre-AIA 35 U.S.C. 103(c), the subject matter which would otherwise qualify as pre-AIA 35 U.S.C. 102(e), (f), or (g) prior art to the claimed invention and the claimed invention must be commonly owned, or subject to an obligation of assignment to the same person, at the time the claimed invention was made or be subject to a joint research agreement at the time the invention was made.

The subject matter and claimed invention must be entirely owned by the same person(s) or organization(s)/business entity(ies) to qualify as common ownership under pre-AIA 35 U.S.C. 102(e), (f), or (g).

The term “commonly owned” is intended to mean that the subject matter which would otherwise pre-AIA 35 U.S.C. 102(e), (f), or (g) prior art to the claimed invention and the claimed invention are entirely or wholly owned by, or under an obligation to assign to, the same person(s) or organization(s)/business entity(ies). For purposes of pre-AIA 35 U.S.C. 103(c), common ownership must be at the time the claimed invention was made. If the person(s) or organization(s) owned less than 100 percent of the subject matter which would otherwise pre-AIA 35 U.S.C. 102(e), (f), or (g) prior art to the claimed invention, or less than 100 percent of the claimed invention, then common ownership would not exist. Common ownership requires that the person(s) or organization(s)/business entity(ies) own 100 percent of the subject matter and 100 percent of the claimed invention.

Determine Common Ownership on Case Facts
Note:
The existence of common ownership at the time an invention was made must be determined based on the specific facts of each case. Both actual ownership and legal obligations to assign both subject matter and the claimed invention are required.

The question of whether common ownership exists at the time the claimed invention was made is to be determined on the facts of the particular case in question. Actual ownership of the subject matter and the claimed invention by the same individual(s) or organization(s) or a legal obligation to assign both the subject matter and the claimed invention to the same individual(s) or organization(s)/business entity(ies) must be in existence at the time the claimed invention was made in order for the subject matter to be disqualified as prior art. A moral or unenforceable obligation would not provide the basis for common ownership.

Admission of Prior Development Not Usable as Prior Art If Invention and Subject Matter Were Commonly Owned
Note:
An applicant’s admission that subject matter was developed prior to the invention cannot be used as prior art for obviousness analysis if the subject matter qualifies as prior art only under sections pre-AIA 35 U.S.C. 102(e), (f), or (g) and both were commonly owned at the time of invention.

Under pre-AIA 35 U.S.C. 103(c), an applicant’s admission that subject matter was developed prior to the invention would not make the subject matter prior art to the application for obviousness analysis if the subject matter qualifies as prior art only under sections pre-AIA 35 U.S.C. 102(e), (f), or (g), and if the subject matter and the claimed invention were commonly owned at the time the invention was made. See In re Fout, 675 F.2d 297, 213 USPQ 532 (CCPA 1982), for a decision involving an applicant’s admission which was used as prior art against their application.

Burden of Proving Common Ownership for Prior Art Disqualification
Note:
Patent applicants must prove that subject matter was commonly owned at the time the claimed invention was made to disqualify it as prior art, not placing this burden on patent examiners or defendants in litigation.

The burden of establishing that subject matter is disqualified as prior art under pre-AIA 35 U.S.C. 103(c) is intended to be placed and reside upon the person or persons urging that the subject matter is disqualified. For example, a patent applicant urging that subject matter is disqualified as prior art under pre-AIA 35 U.S.C. 103(c), would have the burden of establishing that it was commonly owned at the time the claimed invention was made. To place the burden upon the patent examiner or the defendant in litigation would not be appropriate since evidence as to common ownership at the time the claimed invention was made might not be available to the patent examiner or the defendant in litigation, but such evidence, if it exists, should be readily available to the patent applicant or the patentee.

Execution Dates May Not Reflect Assignment Obligation Date
Note:
Examiners should note that dates in assignment documents may not indicate when a party was obligated to assign the claimed invention.

In rare instances, the examiner may have independent evidence that raises a material doubt as to the accuracy of applicant’s representation of either (1) the common ownership of, or (2) the existence of an obligation to commonly assign, the application being examined and the applied U.S. patent or U.S. patent application publication reference. In such cases, the examiner may explain why the accuracy of the representation is doubted. The examiner may also require objective evidence of common ownership of, or the existence of an obligation to assign, the application being examined and the applied reference as of the date of invention of the application being examined. Examiners should note that the execution dates in assignment documents may not reflect the date a party was under an obligation to assign the claimed invention.

Burden on Applicant to Prove Joint Research Agreement
Note:
The applicant must prove a joint research agreement was in effect before the claimed invention was made to overcome an obviousness rejection.

Once an examiner has established a prima facie case of obviousness under pre-AIA 35 U.S.C. 103(a), the burden of overcoming the rejection by invoking the joint research agreement provisions of pre-AIA 35 U.S.C. 103(c) as amended by the CREATE Act is on the applicant or the patentee. Pre-AIA 35 U.S.C. 103(c)(3) defines a “joint research agreement” as a written contract, grant, or cooperative agreement entered into by two or more persons or entities for the performance of experimental, developmental, or research work in the field of the claimed invention, that was in effect on or before the date the claimed invention (under examination or reexamination) was made.

Note:
Applicant must submit a statement indicating that the prior art and claimed invention were made by parties to a joint research agreement within the meaning of pre-AIA 35 U.S.C. 103(c) and as a result of activities undertaken within its scope.

In addition to amending the specification to disclose the names of the parties to the joint research agreement, applicant must submit the required statement to invoke the prior art disqualification under the CREATE Act. 37 CFR 1.104(c)(5) sets forth the requirement for the statement, which includes a statement to the effect that the prior art and the claimed invention were made by or on the behalf of parties to a joint research agreement, within the meaning of pre-AIA 35 U.S.C. 103(c)(3), which was in effect on or before the date the claimed invention was made, and that the claimed invention was made as a result of activities undertaken within the scope of the joint research agreement. The statement should either be on or begin on a separate sheet and must not be directed to other matters (37 CFR 1.4(c)). The statement must be signed in accordance with 37 CFR 1.33(b). As is the case with establishing common ownership, the applicant or patent owner may, but is not required to, present evidence supporting the existence of the joint research agreement.

JRA Does Not Establish Common Ownership for Pre-AIA Prior Art
Note:
Company A cannot use the joint research agreement to disqualify University B’s pre-AIA application as prior art in a rejection under pre-AIA 35 U.S.C. 103(a) because invention X was not made within the scope of the JRA.

Company A and University B have a joint research agreement (JRA) in place prior to the date invention X' was made but the JRA is limited to activities for invention Y, which is distinct from invention X. Professor BB from University B communicates invention X to Company A. On November 12, 2004, University B filed a patent application on invention X. On December 13, 2004, Company A filed a patent application disclosing and claiming invention X', which is an obvious variant of invention X. University B retains ownership of invention X and Company A retains ownership of invention X', without any obligation to assign the inventions to a common owner. Company A could not invoke the joint research agreement provisions of pre-AIA 35 U.S.C. 103(c) to disqualify University B’s application as prior art in a rejection under pre-AIA 35 U.S.C. 103(a) because the claimed invention was not made as a result of the activities undertaken within the scope of the JRA.

Requirement for Same Entities Owning Reference and Application
Note:
Entities must own the same reference as the application at the time of invention to disqualify it as prior art.

Specifically, if an invention claimed in an application is owned by more than one entity and those entities seek to disqualify the use of a reference as prior art under pre-AIA 35 U.S.C. 103(c), then the reference must be owned by, or subject to an obligation of assignment to, the same entities that owned the application, at the time the later invention was made. For example, assume Company A owns twenty percent of patent Application X and Company B owns eighty percent of patent Application X at the time the invention of Application X was made. In addition, assume that Companies A and B seek to disqualify Reference Z as prior art under pre-AIA 35 U.S.C. 103(c). Reference Z must have been co-owned, or have been under an obligation of assignment to both companies, on the date the invention was made in order for the disqualification to be properly requested. A statement such as “Application X and Patent Z were, at the time the invention of Application X was made, jointly owned by Companies A and B” would be sufficient to establish common ownership.

For applications owned by a joint venture of two or more entities, both the application and the reference must have been owned by, or subject to an obligation of assignment to, the joint venture at the time the invention was made. For example, if Company A and Company B formed a joint venture, Company C, both Application X and Reference Z must have been owned by, or subject to an obligation of assignment to, Company C at the time the invention was made in order for Reference Z to be properly disqualified as prior art under pre-AIA 35 U.S.C. 103(c). If Company A by itself owned Reference Z at the time the invention of Application X was made and Application X was owned by Company C on the date the invention was made, then disqualification of Reference Z as prior art under pre-AIA 35 U.S.C. 103(c) would not be proper.

For applications owned by a joint venture of two or more entities, both the application and the reference must have been owned by, or subject to an obligation of assignment to, the joint venture at the time the invention was made. For example, if Company A and Company B formed a joint venture, Company C, both Application X and Reference Z must have been owned by, or subject to an obligation of assignment to, Company C at the time the invention was made in order for Reference Z to be properly disqualified as prior art under pre-AIA 35 U.S.C. 103(c).

Nonstatutory Double Patenting Rejections and Terminal Disclaimers
Note:
The Director may reject claims in commonly owned applications of different inventive entities on grounds of nonstatutory double patenting, which can be overcome by filing terminal disclaimers.

In view of pre-AIA 35 U.S.C. 103(c), the Director has reinstituted in appropriate circumstances the practice of rejecting claims in commonly owned applications of different inventive entities on the grounds of nonstatutory double patenting. Such rejections can be overcome in appropriate circumstances by the filing of terminal disclaimers. This practice has been judicially authorized. See In re Bowers, 359 F.2d 886, 149 USPQ 57 (CCPA 1966). The use of nonstatutory double patenting rejections which then could be overcome by terminal disclaimers precludes patent protection from being improperly extended while still permitting inventors and their assignees to obtain the legitimate benefits from their contributions.

Evidence for Joint Research Agreement Optional
Note:
The applicant may but is not required to provide evidence supporting the existence of a joint research agreement when invoking prior art disqualification under the CREATE Act.

In addition to amending the specification to disclose the names of the parties to the joint research agreement, applicant must submit the required statement to invoke the prior art disqualification under the CREATE Act. 37 CFR 1.104(c)(5) sets forth the requirement for the statement, which includes a statement to the effect that the prior art and the claimed invention were made by or on the behalf of parties to a joint research agreement, within the meaning of pre-AIA 35 U.S.C. 103(c)(3), which was in effect on or before the date the claimed invention was made, and that the claimed invention was made as a result of activities undertaken within the scope of the joint research agreement. The statement should either be on or begin on a separate sheet and must not be directed to other matters (37 CFR 1.4(c)). The statement must be signed in accordance with 37 CFR 1.33(b). As is the case with establishing common ownership, the applicant or patent owner may, but is not required to, present evidence supporting the existence of the joint research agreement.

Application and Prior Art Treated as Commonly Owned
Note:
If the applicant disqualifies the examiner's reliance on pre-AIA 35 U.S.C. 103(c) subject matter, the application and prior art are treated as commonly owned for purposes of pre-AIA 35 U.S.C. 103(a).

If the applicant disqualifies the subject matter relied upon by the examiner in accordance with pre-AIA 35 U.S.C. 103(c) as amended by the CREATE Act and the procedures set forth in the rules, the examiner will treat the application under examination and the pre-AIA 35 U.S.C. 102(e), (f), or (g) prior art as if they are commonly owned for purposes of pre-AIA 35 U.S.C. 103(a).

Admission of Non-Commonly Owned Subject Matter as Prior Art
Note:
If the subject matter and invention were not commonly owned, an admission that the subject matter is prior art can be used in pre-AIA 35 U.S.C. 103 obviousness analysis.

Under pre-AIA 35 U.S.C. 103(c), an applicant’s admission that subject matter was developed prior to the invention would not make the subject matter prior art to the application for obviousness analysis if the subject matter qualifies as prior art only under sections pre-AIA 35 U.S.C. 102(e), (f), or (g), and if the subject matter and the claimed invention were commonly owned at the time the invention was made. See In re Fout, 675 F.2d 297, 213 USPQ 532 (CCPA 1982), for a decision involving an applicant’s admission which was used as prior art against their application. If the subject matter and invention were not commonly owned, an admission that the subject matter is prior art would be usable under pre-AIA 35 U.S.C. 103.

Requirement for Common Ownership at Time of Later Invention
Note:
The examiner must examine the application under pre-AIA 35 U.S.C. 102(e), (f) and (g) only if common ownership is established at the time the later invention was made.

The examiner must examine the application as to all grounds except pre-AIA 35 U.S.C. 102(e), (f) and (g) as they apply through pre-AIA 35 U.S.C. 103(a) only if the application file(s) establishes common ownership at the time the later invention was made. Thus, it is necessary to look to the time at which common ownership exists. If common ownership does not exist at the time the later invention was made, the earlier invention is not disqualified as potential prior art under pre-AIA 35 U.S.C. 102(e), (f) and (g) as they apply through pre-AIA 35 U.S.C. 103(a). An invention is “made” when conception is complete as defined in Mergenthaler v. Scudder, 11 App. D.C. 264, 81 OG 1417, 1897 C.D. 724 (D.C. Cir. 1897); In re Tansel, 253 F.2d 241, 117 USPQ 188 (CCPA 1958). See Pfaff v. Wells Elecs., 525 U.S. 55, 48 USPQ2d 1641, 1647 (1998) (“the invention must be ready for patenting…. by proof that prior to the critical date the inventor had prepared drawings or other descriptions of the invention that were sufficiently specific to enable a person skilled in the art to practice the invention.”) Common ownership at the time the invention was made for purposes of obviating a rejection under pre-AIA 35 U.S.C. 103(a) based on prior art under pre-AIA 35 U.S.C. 102(e), (f) or (g) may be established irrespective of whether the invention was made in the United States or abroad. The provisions of pre-AIA 35 U.S.C. 104, however, will continue to apply to other proceedings in the U.S. Patent and Trademark Office, e.g. in an interference proceeding, with regard to establishing a date of invention by knowledge or use thereof, or other activity with respect thereto, in a foreign country, except the provisions do not apply to applications subject to the current 35 U.S.C. 102 as pre-AIA 35 U.S.C. 104 was repealed effective March 16, 2013. The foreign filing date will continue to be used for interference purposes under 35 U.S.C. 119(a) – (d) and 35 U.S.C. 365.

New Nonstatutory Double Patenting Rejection After Amendment
Note:
If an amendment under 37 CFR 1.71(g) overcomes a pre-AIA 35 U.S.C. 103 rejection based on prior art, the examiner may issue a final Office action with a new nonstatutory double patenting rejection if no other new grounds are introduced.

If an amendment under 37 CFR 1.71(g) is submitted to overcome a rejection under pre-AIA 35 U.S.C. 103(a) based upon a U.S. patent or U.S. patent application publication which qualifies as prior art only under pre-AIA 35 U.S.C. 102(e), and the examiner withdraws the rejection under pre-AIA 35 U.S.C. 103(a), the examiner may need to issue an Office action containing a new nonstatutory double patenting rejection based upon the disqualified patent or patent application publication. In these situations, such Office action can be made final, provided that the examiner introduces no other new ground of rejection that was not necessitated by either amendment or an information disclosure statement filed during the time period set forth in 37 CFR 1.97(c) with the fee set forth in 37 CFR 1.17(p). The Office action is properly made final because the new nonstatutory double patenting rejection was necessitated by amendment of the application by applicant. This is the case regardless of whether the claims themselves have been amended.

If an amendment under 37 CFR 1.71(g) is submitted to overcome a rejection under pre-AIA 35 U.S.C. 103(a) based upon a U.S. patent or U.S. patent application publication which qualifies as prior art only under pre-AIA 35 U.S.C. 102(e), and the examiner withdraws the rejection under pre-AIA 35 U.S.C. 103(a), the examiner may need to issue an Office action containing a new nonstatutory double patenting rejection based upon the disqualified patent or patent application publication. In these situations, such Office action can be made final, provided that the examiner introduces no other new ground of rejection that was not necessitated by either amendment or an information disclosure statement filed during the time period set forth in 37 CFR 1.97(c) with the fee set forth in 37 CFR 1.17(p). The Office action is properly made final because the new nonstatutory double patenting rejection was necessitated by amendment of the application by applicant. This is the case regardless of whether the claims themselves have been amended.

Invention Made When Conception Is Complete
Note:
An invention is considered made when conception is complete, as defined by Mergenthaler v. Scudder and In re Tansel.

The examiner must examine the application as to all grounds except pre-AIA 35 U.S.C. 102(e), (f) and (g) as they apply through pre-AIA 35 U.S.C. 103(a) only if the application file(s) establishes common ownership at the time the later invention was made. Thus, it is necessary to look to the time at which common ownership exists. If common ownership does not exist at the time the later invention was made, the earlier invention is not disqualified as potential prior art under pre-AIA 35 U.S.C. 102(e), (f) and (g) as they apply through pre-AIA 35 U.S.C. 103(a). An invention is “made” when conception is complete as defined in Mergenthaler v. Scudder, 11 App. D.C. 264, 81 OG 1417, 1897 C.D. 724 (D.C. Cir. 1897); In re Tansel, 253 F.2d 241, 117 USPQ 188 (CCPA 1958). See Pfaff v. Wells Elecs., 525 U.S. 55, 48 USPQ2d 1641, 1647 (1998) (“the invention must be ready for patenting…. by proof that prior to the critical date the inventor had prepared drawings or other descriptions of the invention that were sufficiently specific to enable a person skilled in the art to practice the invention.”) Common ownership at the time the invention was made for purposes of obviating a rejection under pre-AIA 35 U.S.C. 103(a) based on prior art under pre-AIA 35 U.S.C. 102(e), (f) or (g) may be established irrespective of whether the invention was made in the United States or abroad. The provisions of pre-AIA 35 U.S.C. 104, however, will continue to apply to other proceedings in the U.S. Patent and Trademark Office, e.g. in an interference proceeding, with regard to establishing a date of invention by knowledge or use thereof, or other activity with respect thereto, in a foreign country, except the provisions do not apply to applications subject to the current 35 U.S.C. 102 as pre-AIA 35 U.S.C. 104 was repealed effective March 16, 2013. The foreign filing date will continue to be used for interference purposes under 35 U.S.C. 119(a) – (d) and 35 U.S.C. 365.

Statement of Common Ownership Required for Assignments
Note:
Applicants must make a signed statement that an application and reference were owned by the same person at the time the invention was made to establish common ownership.

Applications and references (whether patents, patent applications, patent application publications, etc.) will be considered by the examiner to be owned by, or subject to an obligation of assignment to the same person, at the time the invention was made, if the applicant(s) or patent owner(s) make(s) a statement to the effect that the application and the reference were, at the time the invention was made, owned by, or subject to an obligation of assignment to, the same person. The statement must be signed in accordance with 37 CFR 1.33(b). See “Guidelines Setting Forth a Modified Policy Concerning the Evidence of Common Ownership, or an Obligation of Assignment to the Same Person, as Required by 35 U.S.C. 103(c),” 1241 OG 96 (December 26, 2000). The applicant(s) or the representative(s) have the best knowledge of the ownership of their application(s) and reference(s), and their statement of such is sufficient because of their paramount obligation of candor and good faith to the USPTO.

Note:
Applicant must submit a statement to invoke prior art disqualification under the CREATE Act, signed in accordance with 37 CFR 1.33(b).

In addition to amending the specification to disclose the names of the parties to the joint research agreement, applicant must submit the required statement to invoke the prior art disqualification under the CREATE Act. 37 CFR 1.104(c)(5) sets forth the requirement for the statement, which includes a statement to the effect that the prior art and the claimed invention were made by or on the behalf of parties to a joint research agreement, within the meaning of pre-AIA 35 U.S.C. 103(c)(3), which was in effect on or before the date the claimed invention was made, and that the claimed invention was made as a result of activities undertaken within the scope of the joint research agreement. The statement should either be on or begin on a separate sheet and must not be directed to other matters (37 CFR 1.4(c)). The statement must be signed in accordance with 37 CFR 1.33(b). As is the case with establishing common ownership, the applicant or patent owner may, but is not required to, present evidence supporting the existence of the joint research agreement.

After-Final Amendment Requirements
Note:
This rule requires that any amendment after final rejection comply with specific practice rules, such as those found in 37 CFR 1.116, 1.121, and 1.312.

The submission of such an amendment remains subject to the rules of practice: e.g., 37 CFR 1.116, 1.121, and 1.312. For example, if an amendment under 37 CFR 1.71(g) is submitted in an application under final rejection to overcome a rejection under pre-AIA 35 U.S.C. 103(a) based upon a U.S. patent which qualifies as prior art only under pre-AIA 35 U.S.C. 102(e), the examiner may refuse to enter the amendment under 37 CFR 1.71(g) if it is not accompanied by an appropriate terminal disclaimer (37 CFR 1.321(d)). This is because such an amendment may necessitate the reopening of prosecution (e.g., for entry of a nonstatutory double patenting rejection).

Examiner May Question Common Ownership or Assignment Obligation
Note:
The examiner can doubt the accuracy of common ownership or assignment obligations and require objective evidence if independent evidence raises a material doubt.

In rare instances, the examiner may have independent evidence that raises a material doubt as to the accuracy of applicant’s representation of either (1) the common ownership of, or (2) the existence of an obligation to commonly assign, the application being examined and the applied U.S. patent or U.S. patent application publication reference. In such cases, the examiner may explain why the accuracy of the representation is doubted. The examiner may also require objective evidence of common ownership of, or the existence of an obligation to assign, the application being examined and the applied reference as of the date of invention of the application being examined. Examiners should note that the execution dates in assignment documents may not reflect the date a party was under an obligation to assign the claimed invention.

Joint Research Agreement Requirement Before Effective Date
Note:
The joint research agreement must be in effect before the effective date of the CREATE Act but does not need to be active on the prior art reference date.

Like the common ownership or assignment provision, the joint research agreement must be shown to be in effect on or before the time the later invention was made.

Requirement for Complying with Statute and Rules of Practice
Note:
To overcome a rejection based on prior art under pre-AIA 35 U.S.C. 102(e), (f), or (g), the applicant must adhere to the relevant statute and rules of practice.

To overcome a rejection under pre-AIA 35 U.S.C. 103(a) based upon subject matter (whether a patent document, publication, or other evidence) which qualifies as prior art under only one or more of pre-AIA 35 U.S.C. 102(e), (f), or (g) via the CREATE Act, the applicant must comply with the statute and the rules of practice in effect.

Amendment After Grant Requires Certificate of Correction
Note:
If an amendment is not filed until after the patent grant date (post-2004), it must be corrected by a certificate of correction to take advantage of pre-AIA 35 U.S.C. 103(c) without filing a reissue application or request for reexamination.

37 CFR 1.71(g)(3) provides that if an amendment under 37 CFR 1.71(g)(1) is filed after the date the issue fee is paid, the patent as issued may not necessarily include the names of the parties to the joint research agreement. 37 CFR 1.71(g)(3) also provides that if the patent as issued does not include the names of the parties to the joint research agreement, the patent must be corrected to include the names of the parties to the joint research agreement by a certificate of correction under 35 U.S.C. 255 and 37 CFR 1.323 for the amendment to be effective. The requirements of 37 CFR 1.71(g)(3) (correction of the patent by a certificate of correction under 35 U.S.C. 255 and 37 CFR 1.323) also apply in the situation in which such an amendment is not filed until after the date the patent was granted (in a patent granted on or after December 10, 2004). It is unnecessary to file a reissue application or request for reexamination of the patent to submit the amendment and other information necessary to take advantage of pre-AIA 35 U.S.C. 103(c) as amended by the CREATE Act. See H.R. Rep. No. 108-425, at 9 (“[t]he omission of the names of parties to the agreement is not an error that would justify commencement of a reissue or reexamination proceeding”).

Omission of Party Names Not Justifying Reissue or Reexamination
Note:
The omission of party names in a joint research agreement does not warrant initiating reissue or reexamination proceedings.

37 CFR 1.71(g)(3) provides that if an amendment under 37 CFR 1.71(g)(1) is filed after the date the issue fee is paid, the patent as issued may not necessarily include the names of the parties to the joint research agreement. 37 CFR 1.71(g)(3) also provides that if the patent as issued does not include the names of the parties to the joint research agreement, the patent must be corrected to include the names of the parties to the joint research agreement by a certificate of correction under 35 U.S.C. 255 and 37 CFR 1.323 for the amendment to be effective. The requirements of 37 CFR 1.71(g)(3) (correction of the patent by a certificate of correction under 35 U.S.C. 255 and 37 CFR 1.323) also apply in the situation in which such an amendment is not filed until after the date the patent was granted (in a patent granted on or after December 10, 2004). It is unnecessary to file a reissue application or request for reexamination of the patent to submit the amendment and other information necessary to take advantage of pre-AIA 35 U.S.C. 103(c) as amended by the CREATE Act.

Statement Required for Prior Art Disqualification Under CREATE Act
Note:
Applicant must submit a statement disclosing the parties to the joint research agreement and confirming the claimed invention was made within its scope.

In addition to amending the specification to disclose the names of the parties to the joint research agreement, applicant must submit the required statement to invoke the prior art disqualification under the CREATE Act. 37 CFR 1.104(c)(5) sets forth the requirement for the statement, which includes a statement to the effect that the prior art and the claimed invention were made by or on the behalf of parties to a joint research agreement, within the meaning of pre-AIA 35 U.S.C. 103(c)(3), which was in effect on or before the date the claimed invention was made, and that the claimed invention was made as a result of activities undertaken within the scope of the joint research agreement. The statement should either be on or begin on a separate sheet and must not be directed to other matters (37 CFR 1.4(c)). The statement must be signed in accordance with 37 CFR 1.33(b). As is the case with establishing common ownership, the applicant or patent owner may, but is not required to, present evidence supporting the existence of the joint research agreement.
