Joint Inventors

Joint inventorship occurs when two or more persons collaborate to conceive the claimed invention and each contributes to the conception of at least one claim. STATUTORY BASIS: 35 U.S.C. § 116 provides that 'when an invention is made by two or more persons jointly, they shall apply for patent jointly'; CONCEPTION IS THE CRITICAL ELEMENT: inventorship is determined by who CONCEIVED the invention — the mental act of formulating a definite and permanent idea of the complete and operative invention; POSITA STANDARD: the conception must be complete enough that a person of ordinary skill in the art (POSITA) could reduce the invention to practice without extensive experimentation; CONTRIBUTION TO CONCEPTION — NOT JUST REDUCTION TO PRACTICE: a person who merely reduces to practice (builds or tests) an invention already conceived by another is not an inventor; the laboratory technician who runs the experiment designed by the inventor does not become a co-inventor simply by carrying out the experiment; CONTRIBUTION TO AT LEAST ONE CLAIM: a person qualifies as a joint inventor if they contributed to the conception of at least one claim in the patent — they need not have contributed to every claim; if inventor A conceived claims 1–3 and inventor B conceived claims 4–5, both are properly named co-inventors; COLLABORATION NOT REQUIRED: joint inventors need not have worked together at the same time; need not have made the same type or amount of contribution; need not have made a contribution to every claim of the patent; joint inventorship is broader than traditional notions of 'team work' — the contributions can be asynchronous and unequal.

Many individuals contribute to R&D projects without qualifying as inventors: (1) REDUCTION TO PRACTICE WITHOUT CONCEPTION: following the inventor's instructions to build or test a prototype; running experiments designed by the inventor; fabricating components to specifications provided by the inventor; these are contributions of ordinary skill, not inventive conception; (2) SUGGESTING GENERAL GOALS OR RESEARCH DIRECTION: an R&D manager who says 'we should develop a faster algorithm for X' has articulated a goal, not an invention; the person who actually figures out the specific technical solution is the inventor; (3) IDENTIFYING A PROBLEM WITHOUT SOLVING IT: recognizing that a problem exists (even if the problem was unknown in the field) does not constitute inventive contribution if the identifier did not contribute to the solution; (4) PRIOR ART CONTRIBUTIONS: a scientist who contributed to prior art that was used to develop the invention is not a co-inventor of the new invention; their contribution predates and is independent of the claimed invention; (5) ADMINISTRATIVE CONTRIBUTIONS: project management, funding, supervision, or administrative support — even if essential to the project — are not inventive contributions; (6) SUGGESTIONS THAT WERE OBVIOUS TO A POSITA: a suggestion that a POSITA would have considered routine or obvious is not an inventive contribution; the contribution must be beyond what would have been obvious from existing knowledge; WHY THIS MATTERS: incorrectly naming someone as an inventor (improper joinder) or failing to name a true inventor (non-joinder) can invalidate the patent — either through a § 102(f) defense (pre-AIA) or through inequitable conduct if the error was made with deceptive intent.

Inventorship errors can have serious consequences for patent validity and enforceability: PRE-AIA PATENTS (filed before March 16, 2013): under 35 U.S.C. § 102(f) (pre-AIA), a patent is invalid if the named inventor did not invent the claimed subject matter; improper joinder (naming a non-inventor) or non-joinder (omitting a true inventor) could be raised as an invalidity defense in litigation; cure: § 256 allowed correction of inventorship errors without deceptive intent; AIA PATENTS (filed on or after March 16, 2013): § 102(f) was eliminated by the AIA; however, AIA § 115(d) still requires an oath or declaration from each inventor confirming they believe they are original inventors; INEQUITABLE CONDUCT RISK: if inventorship was deliberately misrepresented to the USPTO (e.g., naming a sponsor who didn't invent or excluding a true inventor who holds IP rights that would complicate the application), this may constitute inequitable conduct, rendering the patent unenforceable; Therasense v. Becton Dickinson (Fed. Cir. 2011) set a high bar: but-for materiality AND specific intent to deceive; DISPUTES OVER INVENTORSHIP: inventorship disputes can arise from: employer/employee disagreements; collaborative research agreements where credit is disputed; university-industry partnerships where academic and commercial inventors both contributed; CORRECTION OF INVENTORSHIP: under § 256, inventorship can be corrected administratively if the error was without deceptive intent; requires a request to the USPTO with explanation of the error and, for adding an inventor, a declaration from the added inventor; if litigation is already pending, court orders can also correct inventorship.

Joint patent ownership creates significant co-ownership dynamics that are fundamentally different from joint ownership in other property contexts: EACH CO-OWNER HAS FULL RIGHTS: under 35 U.S.C. § 262, each joint owner of a patent may make, use, sell, and import the patented invention AND may grant non-exclusive licenses to third parties — WITHOUT the consent of the other co-owners and WITHOUT accounting to the other co-owners for the profits; THIS IS A TRAP FOR THE UNWARY: because any joint owner can license without the other's consent, a joint patent can effectively be monetized against the joint owner's wishes; if Company A and Company B are joint owners of a patent, Company A can license the patent to Company C (a competitor of Company B) for any royalty (even $1), and Company B has no recourse; THE CONTRAST WITH COPYRIGHT: in copyright law, joint owners must account to each other for profits; in patent law, they don't have to; CANNOT SUE WITHOUT ALL OWNERS: one co-owner cannot bring a patent infringement lawsuit without joining all other co-owners (mandatory joinder); if one co-owner refuses to join the lawsuit (and has consented to the infringer's conduct via license), the infringement action cannot proceed; PRACTICAL IMPLICATIONS: in collaborative R&D agreements, always address IP ownership; if joint inventorship is expected, specify in the agreement who owns the resulting patents (or assign full ownership to one party in exchange for appropriate compensation or cross-license); university-industry agreements frequently address this — universities often retain patent ownership and grant exclusive licenses.

Joint inventorship arises most commonly in: university-industry collaborations; joint ventures; contractor/vendor development agreements; multi-company consortia; GOVERNING AGREEMENTS: any collaborative R&D arrangement should have a written agreement addressing: (1) IP OWNERSHIP ASSIGNMENT: who owns inventions made by employees of each party during the collaboration? options include: each party owns inventions by its employees; all inventions are jointly owned (dangerous, see above); all inventions are assigned to one party (which may grant back licenses); (2) LICENSE RIGHTS: if joint ownership results, what licenses does each party get? exclusive vs. non-exclusive? field-of-use restrictions? (3) ROYALTY SHARING: if the patent is licensed to third parties, how are royalties split? (4) PROSECUTION CONTROL: who controls prosecution of jointly owned patents? who pays the prosecution and maintenance costs? (5) ENFORCEMENT: who has the right and obligation to enforce jointly owned patents against infringers? WHO IS LIKELY TO BE A JOINT INVENTOR: look at who participated in the inventive activities (lab meetings, design sessions, brainstorming); document creative contributions; avoid naming supervisors or funders who provided only oversight or resources; BEST PRACTICE — INVENTORSHIP REVIEW: after the invention disclosure is drafted, conduct a formal inventorship analysis; for each claim, identify who contributed to the conception of that claim; add only those individuals; exclude those whose contributions were ordinary skill or reduction to practice only.
