Estech Systems IP, LLC v. Zoom Video Communications, Inc.

Background

Estech alleged that Zoom directly infringed claims in three patents: the ’298 Patent, concerning a phone directory in a voice-over-internet-protocol telephone system; the ’684 Patent, concerning quality of service in such a system; and the ’699 Patent, concerning remote voicemail access. Estech also asserted indirect and willful infringement based on Zoom’s telephony products, software, servers, and services.

Zoom moved to dismiss all claims under Federal Rule of Civil Procedure 12(b)(6), which permits dismissal when a complaint does not state a legally sufficient claim. Under the pleading standard discussed by the court, a patent complaint must include enough factual allegations to make infringement plausible. It cannot merely repeat patent-claim elements and conclude that the accused products contain them.

Court’s Analysis

The court held that Estech’s allegations were too conclusory for all three asserted patents. Although Estech identified the patents, representative claims, and approximately 23 Zoom products and services, the complaint did not provide supporting facts tying those products and services to the relevant claim limitations. The court stated that a plaintiff need not plead infringement element by element or provide all information later exchanged under the Local Patent Rules, but it must allege more than the products’ names, general functions, and a conclusion that they infringe.

Because Estech failed to plausibly allege direct infringement, the court also found that its indirect- and willful-infringement claims failed. The opinion states that those claims depended on a plausible direct-infringement claim, which Estech had not pleaded.

Disposition

Judge Edward J. Davila granted Zoom’s motion to dismiss and dismissed Estech’s direct-infringement claim with leave to amend. The court also granted the motion and dismissed Estech’s indirect- and willful-infringement claims with leave to amend. The conclusion states that Zoom’s motion was granted with leave to amend, and it required any amended complaint to be filed within 21 days of the order. The opinion does not state that the dismissals were with prejudice or without prejudice.
