PPC Broadband sued Amphenol Corporation and Times Fiber Communications in the District of Delaware for patent infringement. The case was stayed (and one aggregator lists it as closed); the narrative notes that linkage of U.S. 10,038,284 to this case is inferred from related IPR filings rather than directly confirmed.

PPC Broadband filed a patent infringement action against Amphenol Corporation and Times Fiber Communications in the District of Delaware. The '983 patent was among the patents PPC asserted. The case was stayed pending parallel IPRs, and aggregator data reflects the docket as Closed.

PPC Broadband filed a willful patent infringement suit against CommScope, Inc. in D. Del. It is the second Delaware case flagged in the patent record and in Google Patents litigation links as linked to U.S. Patent No. 9,167,286's litigation family. Listings show the case as closed, but no final judgment or dismissal order details were provided.

PPC Broadband, Inc. sued Amphenol Corporation et al. in the District of Delaware. The case is listed in the family-litigation data for US 9,351,051, but the narrative states that the specific assertion of 9,351,051 was not independently confirmed and that no complaint/exhibit list tying it to the case was retrieved. The case terminated/closed on December 16, 2020.

PPC Broadband sued Times Fiber Communications asserting multiple patents, with infringement of the '353 patent pleaded as Count III. On January 23, 2015, the court approved voluntary dismissal without prejudice of claims and counterclaims relating to the '237, '353, and '060 patents, while the case continued on the '229 patent.

PPC alleged that PerfectVision's SignaLoc connector infringed U.S. Patent 8,366,481, along with claims for negligent misrepresentation, unfair competition, and unfair/deceptive business practices. The case was dismissed under the first-to-file rule in favor of the E.D. Ark. action.

Consolidated Federal Circuit appeals from the Corning IPRs. The court affirmed unpatentability of claims lacking the 'maintain electrical continuity' limitation but vacated the Board's determination that claims 7-27 of the '353 patent were unpatentable, remanding because the Board had not found that Matthews+Tatsuzuki maintain continuity during the claimed positions/modes.

Follow-on Federal Circuit appeal after the remand decisions in the Corning IPRs; Corning withdrew after settlement and the PTO intervened. The opinion restated that the 'maintain electrical continuity' claims require consistent or continuous contact and addressed Board treatment of objective indicia, but the ultimate disposition line was not confirmed from retrieved sources.

Appeal No. 2015-1361, consolidated from IPR2013-00340, -00345, -00346, and -00347. The Federal Circuit affirmed the unpatentability of '320 claims 1-7, 9-15, 17-30, and 32, vacated the unpatentability determination as to claims 8, 16, and 31, and remanded.

Appeal from the Board's decisions on remand in the '320 patent inter partes reviews. The Federal Circuit rejected the Board's reasoning on whether Tatsuzuki's disc-shaped spring would maintain consistent electrical continuity; Corning had settled with PPC and withdrew as a party.
