Review of Specification Required Before Filing
Note:
An attorney or agent must review the specification before filing to ensure it is properly described and compliant with disclosure requirements.

7. Care should be taken to see that prior art or other information cited in a specification or in an information disclosure statement is properly described and that the information is not incorrectly or incompletely characterized. See Apotex v. UCB, Inc., 763 F.3d 1354, 1361-62, 112 USPQ2d 1081, 1087-88 (Fed. Cir. 2014)(finding that the patent specification omitted material information was among the facts that supported a conclusion that the patent is unenforceable due to inequitable conduct). It is particularly important for an attorney or agent to review, before filing, an application which was prepared by someone else, e.g., a foreign applicant or practitioner. It is also important that an attorney or agent make sure that foreign clients, including foreign applicants, attorneys, and agents understand the requirements of the duty of disclosure, and that the U.S. attorney or agent review any information disclosure statements or citations to ensure that compliance with 37 CFR 1.56 is present. See Semiconductor Energy Laboratory Co. v. Samsung Electronics Co., 204 F.3d 1368, 54 USPQ2d 1001 (Fed. Cir. 2000). In this case, during prosecution the patentee submitted an untranslated 29-page Japanese reference as well as a concise explanation of its relevance and an existing one-page partial English translation, both of which were directed to less material portions of the reference. The untranslated portions of the Japanese reference “contained a more complete combination of the elements claimed [in the patent] than anything else before the PTO.” 204 F.3d at 1374, 54 USPQ2d at 1005. The patentee, whose native language was Japanese, was held to have understood the materiality of the reference. “The duty of candor does not require that the applicant translate every foreign reference, but only that the applicant refrain from submitting partial translations and concise explanations that it knows will misdirect the examiner’s attention from the reference’s relevant teaching.” 204 F.3d at 1378, 54 USPQ2d at 1008. See also Gemveto Jewelry Co. v. Lambert Bros., Inc., 542 F. Supp. 933, 216 USPQ 976 (S.D.N.Y. 1982) wherein a patent was held invalid or unenforceable because patentee’s foreign counsel did not disclose to patentee’s United States counsel or to the Office prior art cited by the Dutch Patent Office in connection with the patentee’s corresponding Dutch application. The court stated, 542 F. Supp. at 943, 216 USPQ at 985:

Untranslated Japanese Reference Must Not Misdirect Examiner
Note:
The patentee must ensure untranslated portions of a foreign reference are not submitted if they contain more complete elements than the translated parts, to avoid misguiding the examiner.

Aids to Identifying Prior Art Recommended
Note:
The use of aids is recommended for identifying prior art and may help avoid a ‘fraud’ allegation.

The use of these types of aids would appear to be most helpful, though not required, in identifying prior art and may well help the attorney and the client avoid or more easily explain a potentially embarrassing and harmful “fraud” allegation.

Withheld Reference May Be Highly Material If Discloses More Complete Combination of Features
Note:
A withheld reference may be considered highly material if it discloses a more complete combination of relevant features, even if those features are present in other references.

6. It may be useful to evaluate the materiality of prior art or other information from the viewpoint of whether it is the closest prior art or other information. This will tend to put the prior art or other information in better perspective. See Semiconductor Energy Laboratory Co. v. Samsung Electronics Co., 204 F.3d 1368, 1374, 54 USPQ2d 1001, 1005 (Fed. Cir. 2000) (“A withheld reference may be highly material when it discloses a more complete combination of relevant features, even if those features are before the patent examiner in other references.” (citations omitted)). However, 37 CFR 1.56 may still require the submission of prior art or other information which is not as close as that of record.

Accuracy of Experimental Results Must Be Ensured
Note:
Ensure that experimental results and evidence are accurate, whether inadvertently or intentionally misrepresented.

8. Care should be taken to see that inaccurate statements, inaccurate evidence or inaccurate experiments are not introduced into the record, either inadvertently or intentionally. For example, stating that an experiment “was run” or “was conducted” when, in fact, the experiment was not run or conducted is a misrepresentation of the facts. See Apotex v. UCB, Inc., 763 F.3d 1359, 112 USPQ2d 1085 (Fed. Cir. 2014). No results should be represented as actual results unless they have actually been achieved. Paper or prophetic examples should not be described using the past tense. Hoffman-La Roche, Inc. v. Promega Corp., 323 F.3d 1354, 1367, 66 USPQ2d 1385, 1394 (Fed. Cir. 2003); see also MPEP § 608.01(p), subsection II and § 707.07(l). Also, misrepresentations can occur when experiments which were run or conducted are inaccurately reported in the specification, e.g., an experiment is changed by leaving out one or more ingredients. See Steierman v. Connelly, 192 USPQ 433 (Bd. Pat. Int. 1975); 192 USPQ 446 (Bd. Pat. Int. 1976). Misrepresentations can also occur in declarations submitted to the Office. See Intellect Wireless v. HTC Corp., 732 F. 3d 1339, 1342, 108 USPQ2d 1563, 1565 (Fed.

For example, stating that an experiment “was run” or “was conducted” when, in fact, the experiment was not run or conducted is a misrepresentation of the facts. See Apotex v. UCB, Inc., 763 F.3d 1359, 112 USPQ2d 1085 (Fed. Cir. 2014). No results should be represented as actual results unless they have actually been achieved. Paper or prophetic examples should not be described using the past tense. Hoffman-La Roche, Inc. v. Promega Corp., 323 F.3d 1354, 1367, 66 USPQ2d 1385, 1394 (Fed. Cir. 2003); see also MPEP § 608.01(p), subsection II and § 707.07(l). Also, misrepresentations can occur when experiments which were run or conducted are inaccurately reported in the specification, e.g., an experiment is changed by leaving out one or more ingredients. See Steierman v. Connelly, 192 USPQ 433 (Bd. Pat. Int. 1975); 192 USPQ 446 (Bd. Pat. Int. 1976). Misrepresentations can also occur in declarations submitted to the Office. See Intellect Wireless v.

Duty of Disclosure Fundamentals

6 rules
StatutoryInformativeAlways
[mpep-2004-49ef5fcbd2f2db48189ffbc0]
Duty of Candor Does Not Require Full Translation
Note:
The duty of candor requires applicants to avoid submitting misleading partial translations and concise explanations of foreign references, but not full translations.

7. Care should be taken to see that prior art or other information cited in a specification or in an information disclosure statement is properly described and that the information is not incorrectly or incompletely characterized. See Apotex v. UCB, Inc., 763 F.3d 1354, 1361-62, 112 USPQ2d 1081, 1087-88 (Fed. Cir. 2014)(finding that the patent specification omitted material information was among the facts that supported a conclusion that the patent is unenforceable due to inequitable conduct). It is particularly important for an attorney or agent to review, before filing, an application which was prepared by someone else, e.g., a foreign applicant or practitioner. It is also important that an attorney or agent make sure that foreign clients, including foreign applicants, attorneys, and agents understand the requirements of the duty of disclosure, and that the U.S. attorney or agent review any information disclosure statements or citations to ensure that compliance with 37 CFR 1.56 is present. See Semiconductor Energy Laboratory Co. v. Samsung Electronics Co., 204 F.3d 1368, 54 USPQ2d 1001 (Fed. Cir. 2000). In this case, during prosecution the patentee submitted an untranslated 29-page Japanese reference as well as a concise explanation of its relevance and an existing one-page partial English translation, both of which were directed to less material portions of the reference. The untranslated portions of the Japanese reference “contained a more complete combination of the elements claimed [in the patent] than anything else before the PTO.” 204 F.3d at 1374, 54 USPQ2d at 1005. The patentee, whose native language was Japanese, was held to have understood the materiality of the reference. “The duty of candor does not require that the applicant translate every foreign reference, but only that the applicant refrain from submitting partial translations and concise explanations that it knows will misdirect the examiner’s attention from the reference’s relevant teaching.” 204 F.3d at 1378, 54 USPQ2d at 1008. See also Gemveto Jewelry Co. v. Lambert Bros., Inc., 542 F. Supp. 933, 216 USPQ 976 (S.D.N.Y. 1982) wherein a patent was held invalid or unenforceable because patentee’s foreign counsel did not disclose to patentee’s United States counsel or to the Office prior art cited by the Dutch Patent Office in connection with the patentee’s corresponding Dutch application. The court stated, 542 F. Supp. at 943, 216 USPQ at 985:

Evaluate Materiality of Closest Prior Art
Note:
This rule suggests evaluating the materiality of prior art by considering if it is the closest prior art, which helps put the prior art in better perspective.

6. It may be useful to evaluate the materiality of prior art or other information from the viewpoint of whether it is the closest prior art or other information. This will tend to put the prior art or other information in better perspective. See Semiconductor Energy Laboratory Co. v. Samsung Electronics Co., 204 F.3d 1368, 1374, 54 USPQ2d 1001, 1005 (Fed. Cir. 2000) (“A withheld reference may be highly material when it discloses a more complete combination of relevant features, even if those features are before the patent examiner in other references.” (citations omitted)). However, 37 CFR 1.56 may still require the submission of prior art or other information which is not as close as that of record.

Properly Describe Cited Information
Note:
Ensure that prior art and other information cited in a specification are accurately described to avoid inequitable conduct.

7. Care should be taken to see that prior art or other information cited in a specification or in an information disclosure statement is properly described and that the information is not incorrectly or incompletely characterized. See Apotex v. UCB, Inc., 763 F.3d 1354, 1361-62, 112 USPQ2d 1081, 1087-88 (Fed. Cir. 2014)(finding that the patent specification omitted material information was among the facts that supported a conclusion that the patent is unenforceable due to inequitable conduct). It is particularly important for an attorney or agent to review, before filing, an application which was prepared by someone else, e.g., a foreign applicant or practitioner. It is also important that an attorney or agent make sure that foreign clients, including foreign applicants, attorneys, and agents understand the requirements of the duty of disclosure, and that the U.S. attorney or agent review any information disclosure statements or citations to ensure that compliance with 37 CFR 1.56 is present. See Semiconductor Energy Laboratory Co. v. Samsung Electronics Co., 204 F.3d 1368, 54 USPQ2d 1001 (Fed. Cir. 2000). In this case, during prosecution the patentee submitted an untranslated 29-page Japanese reference as well as a concise explanation of its relevance and an existing one-page partial English translation, both of which were directed to less material portions of the reference. The untranslated portions of the Japanese reference “contained a more complete combination of the elements claimed [in the patent] than anything else before the PTO.” 204 F.3d at 1374, 54 USPQ2d at 1005. The patentee, whose native language was Japanese, was held to have understood the materiality of the reference. “The duty of candor does not require that the applicant translate every foreign reference, but only that the applicant refrain from submitting partial translations and concise explanations that it knows will misdirect the examiner’s attention from the reference’s relevant teaching.” 204 F.3d at 1378, 54 USPQ2d at 1008. See also Gemveto Jewelry Co. v. Lambert Bros., Inc., 542 F. Supp. 933, 216 USPQ 976 (S.D.N.Y. 1982) wherein a patent was held invalid or unenforceable because patentee’s foreign counsel did not disclose to patentee’s United States counsel or to the Office prior art cited by the Dutch Patent Office in connection with the patentee’s corresponding Dutch application.

Proper Description of Foreign References During Prosecution
Note:
Patentees must properly describe and ensure accurate characterization of foreign references submitted during prosecution, including providing complete translations if necessary.

7. Care should be taken to see that prior art or other information cited in a specification or in an information disclosure statement is properly described and that the information is not incorrectly or incompletely characterized. See Apotex v. UCB, Inc., 763 F.3d 1354, 1361-62, 112 USPQ2d 1081, 1087-88 (Fed.

Specification Must Accurately Report Experiments
Note:
The specification must accurately report experiments, including all ingredients used and actual results achieved.

8. Care should be taken to see that inaccurate statements, inaccurate evidence or inaccurate experiments are not introduced into the record, either inadvertently or intentionally. For example, stating that an experiment “was run” or “was conducted” when, in fact, the experiment was not run or conducted is a misrepresentation of the facts. See Apotex v. UCB, Inc., 763 F.3d 1359, 112 USPQ2d 1085 (Fed. Cir. 2014). No results should be represented as actual results unless they have actually been achieved. Paper or prophetic examples should not be described using the past tense. Hoffman-La Roche, Inc. v. Promega Corp., 323 F.3d 1354, 1367, 66 USPQ2d 1385, 1394 (Fed. Cir. 2003); see also MPEP § 608.01(p), subsection II and § 707.07(l). Also, misrepresentations can occur when experiments which were run or conducted are inaccurately reported in the specification, e.g., an experiment is changed by leaving out one or more ingredients. See Steierman v. Connelly, 192 USPQ 433 (Bd. Pat. Int. 1975); 192 USPQ 446 (Bd. Pat. Int. 1976). Misrepresentations can also occur in declarations submitted to the Office. See Intellect Wireless v. HTC Corp., 732 F. 3d 1339, 1342, 108 USPQ2d 1563, 1565 (Fed. Cir. 2013) wherein applicants submitted a declaration under 37 CFR 1.131 containing false statements regarding reduction to practice of the claimed invention.

Copending Application Material to Patentability
Note:
Applicants must inform the examiner of any copending applications that could affect the patentability, even if they cannot shorten the term.

9. Do not rely on the examiner of a particular application to be aware of other applications belonging to the same applicant or assignee. It is desirable to call such applications to the attention of the examiner even if there is only a question that they might be “material to patentability” of the application the examiner is considering. See Dayco Prod., Inc. v. Total Containment, Inc., 329 F.3d 1358, 1365-69, 66 USPQ2d 1801, 1806-08 (Fed. Cir. 2003) (contrary decision of another examiner reviewing substantially similar claims is ‘material’; copending application may be ‘material’ even though it cannot result in a shorter patent term, when it could affect the rights of the patentee to assign the issued patents). It is desirable to be particularly careful that prior art or other information in one application is cited to the examiner in other applications to which it would be material. Do not assume that an examiner will necessarily remember, when examining a particular application, other applications which the examiner is examining, or has examined. A “lapse on the part of the examiner does not excuse the applicant.” KangaROOS U.S.A., Inc. v. Caldor, Inc., 778 F.2d 1571, 1576, 228 USPQ 32, 35 (Fed. Cir. 1985); see also MPEP § 2001.06(b).
