Infringement of Method Claim Shouldn’t Require a Single Entity

AIPLA believes that the so-called “single entity” rule for deciding method claim infringement under 35 U.S.C. § 271(a), where multiple actors perform the claim steps, as set out in recent Federal Circuit panel decisions as well as in the instant case, is based both on an incorrect construction of Section 271(a) and of the statutory structure of Section 271 as a whole. In concluding that only principles of agency law determine the ambit of such infringement liability, the Federal Circuit has mistakenly strayed from the traditional tort law basis of patent infringement and has created loopholes for method claim infringement that drastically reduce the exclusive rights conferred by validly issued patents – it has, in effect, reduced the scope of method patents until they have little relevancy… Direct infringement should not be limited only to an agency-type relationship between parties…

Supreme Court Hears Argument on Burden of Proof for DJ Plaintiff

The Supreme Court on November 5, 2013, heard oral argument on whether the burden of proof in an action for a declaratory judgment of non-infringement falls on the plaintiff licensee or on the defendant patentee. The debate centered around whether a patentee/defendant sued for a declaratory judgment of non-infringement is required to prove a case of infringement that was neither alleged nor arguably possible where the DJ plaintiff is a licensee. The Petitioner argued that the burden that would be on the patentee as infringement plaintiff does not change when it is a DJ defendant. The Respondent argued that, because the patentee cannot assert an infringement counterclaim against its licensee in good standing, the normal default rule places the burden on the party that initiates the action.

Federal Circuit Puzzles Over Claim Construction Deference

The en banc Federal Circuit on September 13, 2013, heard oral argument on whether to overrule its en banc decision in Cybor Corp. v. FAS Technologies, Inc., 138 F.3d 1448 (Fed. Cir. 1998), and hold that claim construction can involve issues of fact reviewable for clear error, and that it is not entirely an issue of law subject only to de novo review. On appeal is the district court decision that a person of ordinary skill in the art would understand the claim term “voltage source means” to correspond to a rectifier or other voltage supply device. It thus rejected ULT’s argument that the term invokes Section 112 ¶6 and that the claim is invalid for indefiniteness for lack of specific structure in the specification. A Federal Circuit panel reversed in a nonprecedential decision, concluding from a de novo review that “voltage source means” does invoke Section 112 ¶6 and that the claim is invalid for indefiniteness. That panel decision was vacated when the appellate court decided to consider the claim construction issue en banc.
