Lyda v. CBS Corporation, 838 F.3d 1331

Edwin Lyda sued CBS and CBS Interactive alleging infringement of U.S. Patents Nos. 7,434,243 and 7,730,506, which claim methods/systems for real-time audience responses (e.g., voting by device/text) that include steps like inputting an identifier code, transmitting responses, collecting and processing them.
Lyda's Amended Complaint asserted four independent claims (method and system claims treated as method claims) and alleged infringement based on CBS’s operation of the TV show Big Brother and use of text-message voting.
The Amended Complaint alleged that CBS Interactive used independent contractors, who directed unnamed third parties to send text votes using their own or borrowed phones; Lyda claimed these acts were done under the direction or control of CBS/CBS Interactive.
Defendants moved to dismiss under Rule 12(b)(6). The district court found the pleading too vague under Form 18 and dismissed without granting further leave to amend (Lyda declined an earlier offered opportunity to amend again).
On appeal, the Federal Circuit held that joint-infringement claims are not governed by Form 18 and must meet the Twombly/Iqbal plausibility standard; it affirmed dismissal because Lyda failed to plead facts plausibly showing direction/control or other attribution to make all claim steps attributable to CBS.

Issue	Plaintiff's Argument	Defendant's Argument	Held
Whether Form 18 pleading requirements apply to joint infringement claims	Lyda relied on Form 18 (minimal pleading) to support sufficiency	CBS argued Form 18 does not cover joint infringement; Twombly/Iqbal apply	Form 18 does not apply to joint infringement; Twombly/Iqbal govern
Whether Lyda plausibly alleged joint/direct infringement via direction or control	Alleged CBS Interactive controlled independent contractors who controlled third-party voters	CBS argued allegations were conclusory and lacked factual detail tying defendants to each claim step	Allegations were conclusory; failed to plausibly allege direction/control or attribution of all steps
Whether system claims should be treated differently from method claims	Lyda pled both system and method claims as alleging performance of steps	CBS argued system claims here recite method steps and should be treated as method claims	System claims recite method steps and are treated as method claims for joint-infringement analysis
Whether district court abused discretion by denying leave to amend	Lyda previously amended; declined offered chance to amend again and opposed motion	CBS supported dismissal and no further amendment	No abuse of discretion; denial of further leave was proper given procedural choices and futility
