directPacket Research, Inc. v. Polycom, LLC

Background

directPacket Research, Inc. sued Polycom Inc. for allegedly infringing three patents concerning multimedia communication across computer networks. Patent Trial and Appeal Board proceedings found claims in two of the patents unpatentable, and the ’588 patent remained at issue in this case. The ’588 patent describes communicating multimedia data between devices that use different signaling protocols by receiving, detecting, converting, translating, and transmitting the data.

Polycom moved for judgment on the pleadings under Federal Rule of Civil Procedure 12(c), arguing that the ’588 patent claimed patent-ineligible subject matter under 35 U.S.C. § 101. A judgment-on-the-pleadings motion asks whether, based on the pleadings, the moving party is entitled to judgment as a matter of law. The court applied the same general standard used for a motion to dismiss for failure to state a claim.

Timeliness

The court rejected directPacket’s argument that Polycom filed the motion too late. Although the case began in 2019, the parties had litigated in the district court, before the Patent Trial and Appeal Board, and before the Federal Circuit. The district court had stayed the case from January 2020 through January 2023, and Polycom filed its motion one month after matters were resolved in the Federal Circuit. The court also found no meaningful prejudice to directPacket and noted that no trial date had been set.

Patent-Eligibility Analysis

The court used the two-part eligibility test established by the Supreme Court. First, it asked whether the claims were directed to an excluded concept, such as an abstract idea. If so, it asked whether the claims contained an “inventive concept”—an element or combination of elements that added enough to make the abstract idea patent-eligible.

The court selected Claim 1 as representative for the eligibility analysis. It found that the other challenged claims did not add a materially different inventive concept. Claims involving Internet transmission, lookup tables, communication interfaces, protocol signalers, conversion utilities, and computer-program code were treated as variations on the same claimed process rather than claims requiring separate analysis.

At the first step, the court concluded that Claim 1 was directed to the abstract idea of translation. The court analogized translating multimedia data from one protocol into an intermediate protocol and then into another protocol to relay translation between human languages. It rejected directPacket’s argument that the use of an intermediate protocol made the analogy inapplicable. The court also concluded that the generalized steps of receiving, detecting, converting, translating, and transmitting did not make the claim non-abstract, and that the patent did not claim a specific improvement to computer functionality.

At the second step, the court found no inventive concept. The claim used a conventional sequence of functions, generic communication controllers and devices, and ordinary computer and network components. The court concluded that the claim merely applied the abstract idea of translation using techniques that were well understood, routine, and conventional. It therefore found the ’588 patent claims patent-ineligible under Section 101.

Disposition

The court dismissed the first, second, and third claims of the complaint with leave to amend. directPacket could file an amended complaint by October 17, 2023. The court stated that failure to meet that deadline would result in dismissal of those claims under Federal Rule of Civil Procedure 41(b).
