Inventorship Correction

Inventorship is one of the most misunderstood concepts in patent law — it is determined solely by conception of the claimed invention: THE BASIC RULE: an inventor is a person who conceived of at least one claim in the patent; conception is the formation in the mind of the inventor of a definite and permanent idea of the complete and operative invention; WHAT QUALIFIES AS INVENTIVE CONTRIBUTION: (a) CONCEPTION OF A CLAIMED ELEMENT: if a person conceived of an element that appears in at least one claim, they are a co-inventor; (b) COLLABORATION THAT LEADS TO CONCEPTION: working jointly with other inventors to develop the invention qualifies; co-inventors need not have contributed to every claim; (c) REDUCTION TO PRACTICE IS NOT ENOUGH: mere execution of an experiment or reducing the concept to physical form does not make someone an inventor; WHAT DOES NOT QUALIFY AS INVENTIVE CONTRIBUTION: (a) Following instructions from an inventor (lab technician who performs experiments as directed is not an inventor); (b) Funding the research (the person who pays for the research is not automatically an inventor); (c) Supervising or managing the inventors (a manager or PI who doesn't conceive of a claim is not an inventor); (d) Contributing to a project but not to the specific claimed invention; (e) Being the first person to have a vague idea without the required definite and permanent conception; JOINT INVENTORSHIP (§ 116): two or more people are joint inventors if they collaborated to conceive the invention; they do not need to contribute equally; they do not need to work at the same time; they do not need to work physically together; Pannu v. Iolab (Fed. Cir. 1998): a co-inventor must: (1) contribute to the conception of the claimed invention; (2) make a contribution that is not insignificant in quality; (3) do more than merely explain well-known concepts or the state of the art.

Incorrect inventorship — having the wrong inventors named — can have serious legal consequences: UNENFORCEABILITY: a patent obtained with deceptive intent and incorrect inventorship may be unenforceable due to inequitable conduct; Therasense v. Becton Dickinson (Fed. Cir. 2011 en banc): inequitable conduct requires: (1) specific intent to deceive the USPTO; (2) but-for materiality; INVALIDITY IN SOME CIRCUMSTANCES: under pre-AIA law (for patents filed before March 16, 2013): a patent with incorrectly named inventors who did not assign their rights could be invalidated; post-AIA: § 256 correction available without deceptive intent even after issuance; OWNERSHIP DISPUTES: all named inventors are presumed co-owners (§ 262); if someone is incorrectly added as an inventor, they have ownership rights they should not have; if someone is incorrectly omitted, they may lack ownership rights they should have; STANDING TO SUE: all co-inventors are co-owners (absent an assignment); each co-owner can independently practice the patent; to sue for infringement, all co-owners must join the lawsuit (Ethicon v. US Surgical); if an omitted inventor is later identified as a co-inventor, they must be joined as a party to enforce the patent; CO-OWNER LICENSING WITHOUT CONSENT: § 262: co-owners can license without each other's consent; a wrongly named inventor could grant a competitor a license that the real inventors cannot block; BAYH-DOLE ISSUES: for federally funded research, incorrect inventorship on patents subject to Bayh-Dole may affect government rights and march-in rights; PRACTICAL RISK: in litigation, defendants routinely attack inventorship as an invalidity defense; deposing inventors to challenge their conception contributes can undermine enforcement.

Inventorship can be corrected at any time without deceptive intent under 35 U.S.C. § 256: WHEN CORRECTION IS AVAILABLE: § 256 allows correction of inventorship in an issued patent when: (a) there is no deceptive intent; (b) the error occurred without deceptive intent; the statute allows both adding omitted inventors and deleting improperly named inventors; FOR PENDING APPLICATIONS (§ 116): inventorship in a pending application can be corrected by filing a request with a statement that the error occurred without deceptive intent; PROCEDURE FOR ISSUED PATENTS: file a Certificate of Correction with the USPTO; requires: (a) petition requesting correction; (b) statement from each person to be added or deleted acknowledging no deceptive intent; (c) statement from the current named inventors who agree to the correction; (d) fee; USPTO will issue a Certificate of Correction if the requirements are met; DECEPTIVE INTENT BAR: if the incorrect inventorship was intentional — to exclude a co-inventor who would not assign rights, to give ownership to someone who didn't contribute — the correction may be barred or the patent may be unenforceable; REISSUE APPLICATION: if § 256 correction is not available (e.g., deceptive intent bar), a reissue application (35 U.S.C. § 251) may allow correction; reissue can correct inventorship and is available within 2 years of patent issuance (for broadening reissue) or any time (for narrowing); LITIGATION CONTEXT: courts have authority under § 256 to order inventorship correction; a district court can order an omitted inventor added without going through the USPTO administrative process; INTERNATIONAL IMPLICATIONS: other countries have their own inventorship rules and may not automatically reflect a US inventorship correction; PCT and EPO applications may require separate correction procedures.

Claims of omitted inventorship by former employees are common in patent litigation and must be carefully managed: THE EMPLOYMENT CONTEXT: inventors (employees) who left a company without receiving credit for their work, or who believe their contribution was not recognized, may later claim co-inventorship on key patents; EMPLOYEE ASSIGNMENT AGREEMENTS: most employers require employees to assign all inventions made in the course of employment (PIIA/CIIAA); a correctly signed assignment agreement protects against the omitted inventor claiming ownership; BUT INVENTORSHIP AFFECTS OWNERSHIP: even with an assignment, if an employee is a true co-inventor and was omitted, their interest in the patent is flawed; a court could order them named as co-inventor, and the lack of their assignment would make the patent unenforceable against their co-ownership interest; PROVING CO-INVENTORSHIP: an alleged omitted inventor must prove their contribution by clear and convincing evidence; Ethicon v. US Surgical (Fed. Cir. 1998): an omitted inventor who successfully proves co-inventorship becomes a co-owner with the right to independently license; LITIGATION RISK: a successful omitted inventor claim can: (a) force addition of the inventor to the patent; (b) establish co-ownership rights (absent assignment); (c) give the former employee the right to license the patent independently to competitors; PROTECTIVE MEASURES: companies should: (a) maintain detailed lab notebooks and invention records documenting who conceived each claimed element; (b) use invention disclosure forms where inventors identify their specific contributions; (c) ensure all inventors sign assignment agreements and CIIAs at the time of employment; (d) when inventorship disputes arise, address them promptly — don't wait until the patent issues or the employee leaves; DEFENSE AGAINST FALSE CLAIMS: documented evidence of the conception process (lab notebooks, emails, internal presentations with dates) is the best defense against fraudulent omitted inventor claims.

Collaborative research creates inventorship complexity because contributors from different organizations may claim inventorship: JOINT DEVELOPMENT AGREEMENTS (JDAs): research collaborations should have written agreements addressing: (a) how inventorship will be determined (by mutual agreement or independent counsel review); (b) who owns inventions made solely by each party; (c) who owns jointly conceived inventions; (d) each party's obligations to file and prosecute patents; (e) rights to license jointly owned patents; THE JOINT INVENTORSHIP PROBLEM: § 262: each co-owner of a patent can independently license without the other's consent (unless the JDA restricts this); if Company A and Company B jointly conceive an invention, either can license a competitor without the other's permission — a significant IP risk; SOLUTIONS IN JDA DRAFTING: (a) assign all jointly owned IP to one party with license-back to the other; (b) require consent of all parties to license jointly owned patents; (c) designate a lead party responsible for prosecution and enforcement; (d) grant rights of first refusal on the other party's interest; UNIVERSITY-INDUSTRY COLLABORATION: university researchers often co-invent with company personnel; university assignment to a TTO (technology transfer office) requires the company to deal with the TTO; Bayh-Dole: federally funded inventions must be reported to the funding agency; university must disclose, elect title, file patents; company collaborator's rights depend on JDA; INVENTORSHIP vs. OWNERSHIP DISTINCTION: inventorship determines who the inventors are (a legal determination based on conception); ownership determines who holds rights (determined by employment law, assignment agreements, and JDA); a university TTO may OWN a patent even if company employees are listed as inventors, if the inventors assigned their rights to the TTO; CONTRACTOR SITUATIONS: independent contractors may retain ownership unless there is a written assignment; Aalmuhammed v. Lee (9th Cir. 2000): a significant creative contribution to a collaborative work doesn't automatically create co-authorship/co-inventorship status without sufficient collaboration.
