Prior Art Exception

AIA 35 U.S.C. § 102(b) establishes two categories of disclosures that are excluded from prior art status: EXCEPTION 1 — INVENTOR'S OWN DISCLOSURES (§ 102(b)(1)(A)): a disclosure made 1 year or less before the effective filing date (EFD) shall not be prior art if 'the disclosure was made by the inventor or joint inventor or by others who obtained the subject matter disclosed directly or indirectly from the inventor or a joint inventor'; WHO QUALIFIES: the inventor(s) named in the application; parties who received the subject matter from the inventor (e.g., a collaborator who co-authored a paper based on the inventor's work); what counts as 'obtaining from the inventor': the party who disclosed received the subject matter from the inventor, either directly or through a chain of disclosure; TIMING: the disclosure must be within 1 year before the EFD; a disclosure exactly 1 year before = included (the statute says '1 year or less'); a disclosure 366 days before EFD = prior art; EXCEPTION 2 — THIRD-PARTY DISCLOSURES AFTER INVENTOR'S OWN DISCLOSURE (§ 102(b)(1)(B)): a disclosure made 1 year or less before the EFD is NOT prior art if 'the subject matter disclosed had, before such disclosure, been publicly disclosed by the inventor or a joint inventor or another who obtained the subject matter...'; WHAT THIS MEANS: if the inventor published first (creating a § 102(b)(1)(A) exception), any third-party publication of the same subject matter after the inventor's disclosure is ALSO excluded; the inventor's own earlier disclosure 'inoculates' against third-party disclosures of the same subject matter; SUBJECT MATTER MUST BE THE SAME: the third-party disclosure must concern the same subject matter that the inventor previously disclosed; a third-party disclosure of an improvement or different aspect of the same technology is NOT necessarily excluded.

When an examiner cites a reference that may qualify for a § 102(b) exception, the applicant must take affirmative steps to invoke it: BURDEN ON APPLICANT: the USPTO does not automatically apply the § 102(b) exceptions; the applicant must identify and invoke the exception with supporting evidence; ESTABLISHING THE INVENTOR'S OWN DISCLOSURE: the applicant must show: (a) the cited reference is a disclosure by the inventor (or someone who obtained subject matter from the inventor); (b) the disclosure was made within 1 year before the EFD; DECLARATION UNDER 37 C.F.R. § 1.130: the patent owner or inventor submits a declaration (an oath/declaration signed by the applicant or inventor) stating: the disclosure identified by the examiner was made by the inventor; OR the subject matter in the disclosure was obtained from the inventor; attaches a copy of the disclosure; identifies the date of the disclosure; FOR THIRD-PARTY DISCLOSURE EXCEPTION (§ 102(b)(1)(B)): must show: (a) the inventor's OWN earlier disclosure (what date and what content); (b) the cited third-party disclosure was made AFTER the inventor's own disclosure; (c) the third-party disclosure covers the SAME subject matter as the inventor's earlier disclosure; PROOF OF DATE: the declaration must establish the date of the inventor's prior disclosure; contemporaneous evidence (paper submission date; conference date; upload timestamp) is most persuasive; secondary evidence (email chains; lab notebooks; version history) can also support the declaration; EXAMINER'S RESPONSE: the examiner reviews the declaration and evidence; if satisfied, withdraws the § 102 rejection; if not satisfied, maintains the rejection and the applicant may appeal; APPEAL: if the examiner maintains the rejection after invoking § 102(b), the applicant may appeal to the PTAB.

The AIA significantly changed the scope and structure of the grace period from pre-AIA law: PRE-AIA § 102(b) GRACE PERIOD: a patent is not anticipated by activity that occurred more than 1 year before the US filing date; activities covered: patented, described in a printed publication, in public use, on sale in the US; the reference date was measured from the FILING DATE of the US application; no distinction between inventor's own and third-party disclosures within the grace period; a third-party's independent publication less than 1 year before filing DID NOT count as prior art under pre-AIA; AIA § 102(b) GRACE PERIOD: measured from EFFECTIVE FILING DATE (EFD) — which could be a priority date (provisional, PCT, parent); the exception DISTINGUISHES between: inventor's own disclosures (always excluded for 1 year); independent third-party disclosures of the SAME subject matter (only excluded if made AFTER inventor's prior disclosure); independent third-party disclosures of DIFFERENT subject matter (always prior art, even within 1 year of EFD); KEY DIFFERENCE: under pre-AIA, a third party's paper published 11 months before the US filing was NOT prior art (if it was the only disclosure); under AIA, that same paper IS prior art unless the inventor had previously disclosed the SAME subject matter; PRACTICAL EXAMPLE: Inventor A works on Widget. Third Party B independently develops the same Widget and publishes 8 months before A's EFD. A has NOT disclosed Widget before B's publication. Under PRE-AIA: B's publication is NOT prior art (within 1-year grace period). Under AIA: B's publication IS prior art (independent third-party disclosure; A had not previously disclosed).

The scope of Exception 2 (§ 102(b)(1)(B)) depends on whether the third-party disclosure covers the same subject matter as the inventor's prior disclosure: SAME SUBJECT MATTER: the third-party disclosure must be of subject matter that the inventor 'had...publicly disclosed' — meaning essentially the same invention or technology that the inventor disclosed; VERBATIM NOT REQUIRED: the disclosures need not be identical in wording; the subject matter — the technical content — must be the same; DIFFERENCES IN EMPHASIS or CONTEXT: a third-party paper that describes the inventor's disclosed technology in a different context may or may not be 'same subject matter'; the question is whether the technical disclosure is the same; PARTIAL OVERLAP: if the third-party disclosure covers some aspects of the inventor's disclosure AND additional independent aspects, the additional aspects ARE still prior art; only the portions that overlap with the inventor's prior disclosure are excepted; EXAMPLE: Inventor A discloses Widget A with Feature 1 and Feature 2. Third Party B, after seeing A's disclosure, publishes a paper about Widget A with Feature 1 and Feature 2 (same subject matter) PLUS Feature 3 (new). Exception 2 applies to: Feature 1 and Feature 2 as disclosed by B. Feature 3 as disclosed by B is STILL prior art (B independently disclosed it; A had not disclosed Feature 3). PRACTICAL IMPLICATION: inventors should document their disclosure comprehensively to maximize the scope of Exception 2; a detailed inventor disclosure protects more subject matter from subsequent third-party development and publication; USPTO MPEP GUIDANCE: MPEP § 2153.01 and § 2154 address the § 102(b) exceptions in detail; examiners and practitioners should consult MPEP for current USPTO practice.

Complex inventorship situations create nuanced interactions with the § 102(b) exceptions: JOINT INVENTORS: each named inventor (including joint inventors) can invoke the § 102(b)(1)(A) exception for their own disclosures; a disclosure by ONE joint inventor of the joint invention is a disclosure by the inventor for § 102(b) purposes; CORPORATE ASSIGNEES: the § 102(b) exception refers to 'the inventor or joint inventor or others who obtained the subject matter from the inventor'; a company that is the assignee of the invention is not automatically within the exception; BUT: if a corporate employee-inventor makes the disclosure at a company conference, the disclosure is by 'the inventor'; the company's further disclosure of the same subject matter would be 'obtained from the inventor'; THIRD-PARTY DISCLOSURE BY CO-OWNER: if two companies co-own a patent, a disclosure by Company B's employee of subject matter conceived by Company A's employee is only within the exception if it was 'obtained from the inventor' (Company A's employee); CONSULTANT SCENARIO: an inventor uses a consultant who participates in developing the invention; the consultant might be a joint inventor (if they contributed to the conception of a claim); if a joint inventor, their disclosure is within the exception; if only a contractor who implemented (not conceived), their disclosure may not be within the exception; ACADEMIC COLLABORATIONS: a professor-inventor collaborates with a graduate student (who may or may not be a joint inventor); the student's conference presentation of their joint work is within the exception if the student is a named inventor OR if they 'obtained the subject matter from' the named inventor; BEST PRACTICE: document the chain of disclosure from the named inventors to any third party who publicly disclosed the invention; this establishes the 'obtained from the inventor' relationship.
