Times Fiber vs. PPC Broadband: PTAB Invalidates All Asserted Cable Patent Claims
In a decisive outcome for patent defendants leveraging inter partes review, Times Fiber Communications, Inc. v. PPC Broadband, Inc. (Case No. 1:21-cv-01823, D. Del.) concluded with the complete invalidation of every asserted patent claim — without a single day of district court trial. Filed December 27, 2021, in the Delaware District Court and closed March 4, 2024, this **coaxial cable patent infringement** dispute illustrates how strategically deployed IPR petitions can neutralize multi-patent litigation campaigns before they escalate.
Times Fiber asserted five patents against PPC Broadband’s Perfect Flex® Coaxial Cable, Perfect Tote™ 500 Cable Bag, and Reusable Cable Reel Assembly product lines. PPC Broadband responded not by litigating in Delaware, but by taking the fight directly to the Patent Trial and Appeal Board (PTAB) — and winning on every front. For patent attorneys, IP professionals, and R&D leaders operating in the broadband infrastructure and cable hardware space, this case delivers critical lessons about patent prosecution quality, IPR offensive strategy, and litigation risk management.

Case Overview
The Parties
⚖️ Plaintiff
Is a manufacturer and IP holder in the coaxial cable and broadband connectivity space, holding a portfolio of patents directed at cable handling, packaging, and dispensing technologies.
🛡️ Defendant
Is a well-established manufacturer of broadband connectivity products, including coaxial cable assemblies and related accessories widely deployed in telecommunications infrastructure.
Patents at Issue
This landmark case involved five U.S. patents, all directed at coaxial cable handling and dispensing technologies, covering innovations relating to cable reel assemblies, cable dispensing systems, and portable cable management solutions. These technologies have direct commercial relevance to broadband installation and field service operations.

The Verdict & Legal Analysis
Outcome
The case concluded via stipulated dismissal with prejudice under Fed. R. Civ. P. 41, filed February 29, 2024 (D.I. 40). No damages were awarded. No injunctive relief was granted. Each party bore its own costs, expenses, and attorneys’ fees. The dismissal followed a complete and unreversed PTAB determination that all challenged claims across all five asserted patents were unpatentable.
Critically, Times Fiber did not file motions for rehearing or notices of appeal in any IPR proceeding where its claims were found unpatentable — a strategic concession that effectively ended the litigation with no viable path to enforcement.
Verdict Cause Analysis
PPC Broadband’s IPR strategy was comprehensive and decisive. By petitioning for inter partes review of every asserted claim across all five patents simultaneously, PPC created a unified validity challenge that, if successful at PTAB, would structurally collapse the entire infringement case. PTAB’s institution and subsequent finding of unpatentability on all challenged claims accomplished precisely that outcome.
The absence of any appeal by Times Fiber is legally significant. Under 35 U.S.C. § 319 and the Thryv, Inc. v. Click-to-Call Technologies line of authority, PTAB’s final written decisions carry substantial weight, and the estoppel provisions of 35 U.S.C. § 315(e) would have significantly constrained PPC’s exposure in any continued district court proceeding. Faced with cancelled claims and no appeal strategy, Times Fiber had no remaining infringement case to prosecute.
Legal Significance
This outcome reinforces several important doctrinal and procedural principles:
- IPR as a complete defense vector: When a defendant successfully challenges all asserted claims at PTAB, district court litigation becomes moot without reaching claim construction, infringement analysis, or damages.
- Stay pending IPR: Courts — particularly in Delaware — routinely grant stays pending PTAB proceedings when IPR petitions cover all asserted claims, reducing judicial resource expenditure and creating settlement pressure on patentees.
- Patent prosecution quality is litigation-determinative: The invalidation of five related patents suggests potential systemic prosecution vulnerabilities, possibly including prior art not overcome during examination or claim drafting susceptible to obviousness challenges under 35 U.S.C. § 103.
Industry & Competitive Implications
The coaxial cable and broadband connectivity hardware market is characterized by dense patent portfolios, ongoing product innovation, and significant commercial stakes tied to telecommunications infrastructure deployment. Times Fiber v. PPC Broadband reflects a broader assertion pattern in this space where IP holders attempt to protect market position through patent litigation against larger, well-resourced competitors.
PPC Broadband’s successful IPR strategy demonstrates that established broadband hardware manufacturers are investing in sophisticated patent defense capabilities, including proactive PTAB engagement. This signals to would-be plaintiffs that asserted patents in this sector will face rigorous validity scrutiny before infringement questions are ever reached.
For companies in adjacent broadband infrastructure, cable management, and connectivity hardware markets, this case reinforces the importance of patent landscape monitoring and competitive intelligence. When a multi-patent portfolio is invalidated wholesale, it can shift licensing dynamics, affect product pricing freedom, and alter competitive positioning across an entire product category.
The telecom and broadband connectivity sector should anticipate continued IPR activity as the industry undergoes rapid infrastructure expansion driven by fiber broadband deployment and 5G buildout programs.
