DerivationDerivationGambro Lundia v Baxter HealthcareGambro Lundia v Baxter Healthcare (Fed. Cir. 1997) (Fed. Cir. 1997)

• What are the two components of a finding of derivation?• What is the standard for how much information must be

communicated?

• Note: why require corroboration of conception? (What is the practical effect of the corroboration requirement on inventors’ testimony?)

• Is there any real difference between the communication standard used by the D.Ct. and the Gambro court? (What is it?)

• What happens if you prove prior conception by another, but the communication does not enable?

rule?rule?

• Contrast the rule with the Inventorship requirement.

• Consider the ‘bus’ hypothetical on p. 467. o Can you think of reasons we might want to allow

the eavesdropper to get a patent on the invention?o What if the eavesdropper files a patent application

for the invention? What happens to the true inventor?


PriorityPriority35 U.S.C. § 102(g)35 U.S.C. § 102(g)A person shall be entitled to a patent unless . . .A person shall be entitled to a patent unless . . .

(g)(1) during the course of an interference … another inventor involved therein establishes … that before such before such person’s invention thereof the invention was made by person’s invention thereof the invention was made by such other inventor and not abandoned, suppressed, or such other inventor and not abandoned, suppressed, or concealedconcealed, or

(2) before such person’s invention thereof, the invention was made in this country by another inventor who had not abandoned, suppressed, or concealed it.

In determining priority of invention under this In determining priority of invention under this subsection, there shall be considered not only the subsection, there shall be considered not only the respective dates of conception and reduction to practice respective dates of conception and reduction to practice of the invention, but also the reasonable diligence of one of the invention, but also the reasonable diligence of one who was first to conceive and last to reduce to practice, who was first to conceive and last to reduce to practice, from a time prior to conception by the other.from a time prior to conception by the other.


PriorityPrioritySection 102(g) establishes the US system Section 102(g) establishes the US system

as a “first to invent” system.as a “first to invent” system.• Virtually all of the rest of the world has a

“first to file” system.

Consider the relative merits of each Consider the relative merits of each system w/r/t.. system w/r/t.. • Determining the ‘real’ inventor;• Administrative difficulties;• Incentives on the innovation process;• Should we switch to first-to-file?


PriorityPriorityThe Basic Rule of PriorityThe Basic Rule of Priority

RuleRule: First to reduce to practice = priority• Exception A: Prior conception + diligence

until reduction to practice.• Exception B: The original inventor

abandons, suppresses, or conceals her invention.
