Patent Must Issue Before Pre-AIA 102(d) Rejection
Note:
An application must be issued as a patent before it can be used in a pre-AIA 35 U.S.C. 102(d) rejection.

An application must issue into a patent before it can be applied in a pre-AIA 35 U.S.C. 102(d) rejection. Ex parte Fujishiro, 199 USPQ 36 (Bd. App. 1977) (“Patenting,” within the meaning of pre-AIA 35 U.S.C. 102(d), does not occur upon laying open of a Japanese utility model application (kokai or kohyo)); Ex parte Links, 184 USPQ 429 (Bd. App. 1974) (German applications, which have not yet been published for opposition, are published in the form of printed documents called Offenlegungsschriften 18 months after filing. These applications are unexamined or in the process of being examined at the time of publication. The Board held that an Offenlegungsschrift is not a patent under pre-AIA 35 U.S.C. 102(d) even though some provisional rights are granted. The Board explained that the provisional rights are minimal and do not come into force if the application is withdrawn or refused.).

Offenlegungsschrift Is Not a Pre-AIA Patent
Note:
An Offenlegungsschrift, which is published in the form of printed documents for German applications, does not qualify as a patent under pre-AIA 35 U.S.C. 102(d) even if it grants some provisional rights.

Published Application Is Considered a Patent for Rejection Purposes
Note:
An examined application that has been allowed and published is treated as a patent for rejection purposes under pre-AIA 35 U.S.C. 102(d) if substantial provisional enforcement rights arise.

An examined application which has been allowed by the examiner and published to allow the public to oppose the grant of a patent has been held to be a “patent” for purposes of rejection under pre-AIA 35 U.S.C. 102(d) as of the date of publication for opposition if substantial provisional enforcement rights arise. Ex parte Beik, 161 USPQ 795 (Bd. App. 1968) (This case dealt with examined German applications. After a determination that an application is allowable, the application is published in the form of a printed document called an Auslegeschrift. The publication begins a period of opposition were the public can present evidence showing unpatentability. Provisional patent rights are granted which are substantially the same as those available once the opposition period is over and the patent is granted. The Board found that an Auslegeschrift provides the legal effect of a patent for purposes of rejection under pre-AIA 35 U.S.C. 102(d).).

Publication of Allowed Application as Auslegeschrift
Note:

Public Can Present Evidence Showing Unpatentability During Opposition Period
Note:
The public can submit evidence to show that a patent is unpatentable during the opposition period after an application has been published and deemed allowable.

An examined application which has been allowed by the examiner and published to allow the public to oppose the grant of a patent has been held to be a “patent” for purposes of rejection under pre-AIA 35 U.S.C. 102(d) as of the date of publication for opposition if substantial provisional enforcement rights arise.

Filing Deadline Extended to Next Business Day on Holidays
Note:
If the filing deadline falls on a Saturday, Sunday, or federal holiday, it is extended to the next business day.

The U.S. application is filed in time to prevent a pre-AIA 35 U.S.C. 102(d) bar from arising if it is filed on the 1 year anniversary date of the filing date of the foreign application. If this day is a Saturday, Sunday or federal holiday, the year would be extended to the following business day. See Ex parte Olah, 131 USPQ 41 (Bd. App. 1960). Despite changes to 37 CFR 1.6(a)(2) and 37 CFR 1.10, which require the USPTO to accord a filing date to an application as of the date of deposit as Priority Mail Express® with the U.S. Postal Service in accordance with 37 CFR 1.10 (e.g., a Saturday filing date), the rule changes do not affect applicant’s concurrent right to defer the filing of an application until the next business day when the last day for “taking any action” falls on a Saturday, Sunday, or a federal holiday (e.g., the last day of the 1-year grace period falls on a Saturday).

Patent Rights Fixed Upon Grant
Note:
The date patent rights are granted is the relevant date for pre-AIA 35 U.S.C. 102(d) purposes, regardless of publication delays.

A period of secrecy after granting the patent, as in Belgium and Spain, has been held to have no effect in connection with pre-AIA 35 U.S.C. 102(d).

U.S. Claims Must Be Supported by Foreign Patent
Note:
A pre-AIA 35 U.S.C. 102(d) rejection applies if the foreign application supports the subject matter of the U.S. claims, even if the claims are not identical.

Under pre-AIA 35 U.S.C. 102(d), the “invention… patented” in the foreign country must be the same as the invention sought to be patented in the U.S. When the foreign patent contains the same claims as the U.S. application, there is no question that “the invention was first patented… in a foreign country.” In re Kathawala, 9 F.3d 942, 945, 28 USPQ2d 1785, 1787 (Fed. Cir. 1993). However, the claims need not be identical or even within the same statutory class. If applicant is granted a foreign patent which fully discloses the invention and which gives applicant a number of different claiming options in the U.S., the reference in pre-AIA 35 U.S.C. 102(d) to “‘invention… patented’ necessarily includes all the disclosed aspects of the invention. Thus, the [pre-AIA] section 102(d) bar applies regardless whether the foreign patent contains claims to less than all aspects of the invention.” 9 F.3d at 946, 28 USPQ2d at 1788. In essence, a pre-AIA 35 U.S.C. 102(d) rejection applies if applicant’s foreign application supports the subject matter of the U.S. claims. Id. at 944, 947, 28 USPQ2d at 1786, 1789 (Applicant was granted a Spanish patent claiming a method of making a composition. The patent disclosed compounds, methods of use and processes of making the compounds. After the Spanish patent was granted, the applicant filed a U.S. application with claims directed to the compound but not the process of making it. The Federal Circuit held that it did not matter that the claims in the U.S. application were directed to the composition instead of the process because the foreign specification would have supported claims to the composition. It was immaterial that the formulations were unpatentable pharmaceutical compositions in Spain.).

Foreign Patent Can Be Used In Pre-AIA Rejection If Added Claims Are Not Nonobvious
Note:
If a foreign application issues into a patent before the filing date of a CIP, it may be used in a pre-AIA 102(d)/103 rejection if the added claims are not considered nonobvious over the foreign patent.

In the case where applicant files a foreign application, later files a U.S. application claiming priority based on the foreign application, and then files a continuation-in-part (CIP) application whose claims are not entitled to the filing date of the U.S. parent, the effective filing date is the filing date of the CIP and applicant cannot obtain the benefit of either the U.S. parent or foreign application filing dates. In re Van Langenhoven, 458 F.2d 132, 137, 173 USPQ 426, 429 (CCPA 1972). If the foreign application issues into a patent before the filing date of the CIP, it may be used in a pre-AIA 35 U.S.C. 102(d) / 103 rejection if the subject matter added to the CIP does not render the claims nonobvious over the foreign patent. Ex parte Appeal No. 242-47, 196 USPQ 828 (Bd. App. 1976) (Foreign patent can be combined with other prior art to bar a U.S. patent in an obviousness rejection based on pre-AIA 35 U.S.C. 102(d) / 103).

Same Claims as U.S. Application Require Prior Filing
Note:
If a foreign patent contains claims identical to those in a U.S. application, it must be considered for prior filing under pre-AIA 35 U.S.C. 102(d), even if the claims are not identical or within the same statutory class.

Under pre-AIA 35 U.S.C. 102(d), the “invention… patented” in the foreign country must be the same as the invention sought to be patented in the U.S. When the foreign patent contains the same claims as the U.S. application, there is no question that “the invention was first patented… in a foreign country.” In re Kathawala, 9 F.3d 942, 945, 28 USPQ2d 1785, 1787 (Fed.

Under pre-AIA 35 U.S.C. 102(d), the “invention… patented” in the foreign country must be the same as the invention sought to be patented in the U.S. When the foreign patent contains the same claims as the U.S. application, there is no question that “the invention was first patented… in a foreign country.” In re Kathawala, 9 F.3d 942, 945, 28 USPQ2d 1785, 1787 (Fed.

U.S. Application Filing on Foreign Filing Anniversary Prevents Pre-AIA Bar
Note:
The U.S. application must be filed on the one-year anniversary of the foreign filing date to avoid a pre-AIA 102(d) bar, with extensions for holidays.

The U.S. application is filed in time to prevent a pre-AIA 35 U.S.C. 102(d) bar from arising if it is filed on the 1 year anniversary date of the filing date of the foreign application. If this day is a Saturday, Sunday or federal holiday, the year would be extended to the following business day. See Ex parte Olah, 131 USPQ 41 (Bd. App. 1960). Despite changes to 37 CFR 1.6(a)(2) and 37 CFR 1.10, which require the USPTO to accord a filing date to an application as of the date of deposit as Priority Mail Express® with the U.S. Postal Service in accordance with 37 CFR 1.10 (e.g., a Saturday filing date), the rule changes do not affect applicant’s concurrent right to defer the filing of an application until the next business day when the last day for “taking any action” falls on a Saturday, Sunday, or a federal holiday (e.g., the last day of the 1-year grace period falls on a Saturday).

Under pre-AIA 35 U.S.C. 102(d), the “invention… patented” in the foreign country must be the same as the invention sought to be patented in the U.S. When the foreign patent contains the same claims as the U.S. application, there is no question that “the invention was first patented… in a foreign country.” In re Kathawala, 9 F.3d 942, 945, 28 USPQ2d 1785, 1787 (Fed.

Under pre-AIA 35 U.S.C. 102(d), the “invention… patented” in the foreign country must be the same as the invention sought to be patented in the U.S. When the foreign patent contains the same claims as the U.S. application, there is no question that “the invention was first patented… in a foreign country.” In re Kathawala, 9 F.3d 942, 945, 28 USPQ2d 1785, 1787 (Fed. Cir. 1993). However, the claims need not be identical or even within the same statutory class. If applicant is granted a foreign patent which fully discloses the invention and which gives applicant a number of different claiming options in the U.S., the reference in pre-AIA 35 U.S.C. 102(d) to “‘invention… patented’ necessarily includes all the disclosed aspects of the invention. Thus, the [pre-AIA] section 102(d) bar applies regardless whether the foreign patent contains claims to less than all aspects of the invention.” 9 F.3d at 946, 28 USPQ2d at 1788. In essence, a pre-AIA 35 U.S.C. 102(d) rejection applies if applicant’s foreign application supports the subject matter of the U.S. claims. Id. at 944, 947, 28 USPQ2d at 1786, 1789 (Applicant was granted a Spanish patent claiming a method of making a composition. The patent disclosed compounds, methods of use and processes of making the compounds. After the Spanish patent was granted, the applicant filed a U.S. application with claims directed to the compound but not the process of making it. The Federal Circuit held that it did not matter that the claims in the U.S. application were directed to the composition instead of the process because the foreign specification would have supported claims to the composition. It was immaterial that the formulations were unpatentable pharmaceutical compositions in Spain.).

Foreign Specification Supports U.S. Claims Regardless of Formulation Differences
Note:
The Federal Circuit ruled that claims in a U.S. application can be directed to a composition even if the foreign specification supports process claims, as long as the composition is within the disclosed invention.
