PPC Broadband v. PerfectVision: Five-Patent Coaxial Connector Dispute Ends in Prejudicial Dismissal
PPC Broadband filed suit in the Eastern District of Arkansas asserting five US patents against PerfectVision’s SignaLoc PV6USLP coaxial cable connector. After 1,399 days of litigation — nearly four years — both parties stipulated to dismiss all claims and counterclaims with prejudice, each bearing its own costs.
A four-year coaxial connector patent war ends in mutual standdown
PPC Broadband, Inc. — a specialist coaxial cable connector manufacturer — filed suit on 18 February 2022 against PerfectVision Manufacturing, Inc. in the Eastern District of Arkansas before Judge Lee P. Rudofsky. The complaint asserted five US patents: US7479035B2, US10756455B2, US8172612B2, US7114990B2, and US7955126B2, all covering aspects of coaxial cable connector design and construction. The accused product was PerfectVision’s SignaLoc PV6USLP connector model.
The case closed on 18 December 2025 via a Rule 41(a)(1)(A)(ii) stipulated dismissal with prejudice. Both sides signed off on permanent termination of all claims and counterclaims, with each party bearing its own litigation costs, attorney’s fees, and related expenses. A with-prejudice stipulation means PPC Broadband cannot re-file these same claims against PerfectVision on the same patents — the litigation chapter is conclusively closed.
The 1,399-day duration suggests the parties engaged in substantial pretrial activity — likely including claim construction and discovery — before reaching a resolution. The mutual cost-bearing arrangement, absence of any damages award, and simultaneous extinguishment of counterclaims all suggest a negotiated commercial resolution rather than a courtroom victory for either side. The specific commercial terms, if any, remain confidential and are not reflected in the public record.
Filing to Dismissed with Prejudice in 1399 days
1,399 days — nearly 4 years, above the median for multi-patent district court infringement actions
Dismissed with prejudice: what the stipulated exit means for both parties
Rule 41(a)(1)(A)(ii) stipulated dismissal — permanently binding
A Rule 41(a)(1)(A)(ii) dismissal requires both parties’ signatures and, when entered with prejudice, functions as a final adjudication on the merits. PPC Broadband cannot reinstate these five patent claims against PerfectVision in any future action. The simultaneous disposal of all counterclaims mirrors the symmetry of the cost-bearing arrangement — a clean bilateral exit from the litigation.
No re-filing possiblePPC Broadband exits with patents intact but no public enforcement win
Dismissal with prejudice forecloses future action against PerfectVision on these patents, but the underlying patents — US7479035B2, US10756455B2, US8172612B2, US7114990B2, and US7955126B2 — remain valid and enforceable against third parties. PPC retains full freedom to assert these patents in separate proceedings against other accused infringers. The absence of a damages award, however, means no public signal of patent strength emerged from this litigation.
Patents survive; enforcement bar raised vs. PerfectVisionPerfectVision escapes liability — but only for this dispute
PerfectVision Manufacturing avoids any finding of infringement, damages, or injunction relating to the SignaLoc PV6USLP connector. The with-prejudice bar prevents PPC Broadband from reinitiating these specific claims. Counterclaims — likely including invalidity challenges — are also dismissed, meaning the patents’ validity was never adjudicated on the merits. PerfectVision bears no declared obligation, though its own costs over 1,399 days were substantial.
No infringement finding; invalidity left untestedCoaxial connector IP landscape unchanged — uncertainty persists
Because neither infringement nor validity was decided on the merits, the five PPC patents emerge from this case with an unchanged legal status. Competitors and OEM buyers of coaxial connectors cannot draw comfort from this dismissal as a signal that the PPC portfolio is weak. The case’s length and ultimate mutual exit is consistent with a confidential licensing or supply arrangement — a pattern common in hardware component patent disputes where commercial relationships outlast litigation postures.

Official order — verbatim text
The stipulation’s explicit invocation of Rule 41(a)(1)(A)(ii) and the with-prejudice qualifier are legally significant: this is not a unilateral withdrawal but a bilaterally negotiated, court-recognised final disposition. The mutual cost-bearing clause suggests neither party extracted a clear concession from the other in the litigation itself. All five patent claims and all counterclaims — including any invalidity defences PerfectVision had pleaded — are extinguished simultaneously, leaving the underlying patents legally unscathed but commercially tested.
US7479035B2 and four coaxial connector patents — PPC Broadband’s enforcement portfolio
The five asserted patents — US7479035B2, US10756455B2, US8172612B2, US7114990B2, and US7955126B2 — collectively cover the mechanical architecture of coaxial cable connectors used in broadband and CATV distribution networks. These patents protect elements including connector body geometry, coupling nut mechanics, internal post design, and environmental sealing. The application filing dates span from the mid-2000s through to the early 2010s, reflecting PPC Broadband’s sustained R&D investment in precision connector engineering during the rapid expansion of cable broadband infrastructure.
PPC Broadband’s coaxial connector portfolio is strategically significant in a market dominated by a handful of hardware suppliers serving cable MSOs, satellite installers, and broadband infrastructure contractors. The five-patent stack provides overlapping claim coverage — a structure that makes design-arounds more difficult and IPR challenges more expensive for competitors. PerfectVision’s SignaLoc PV6USLP sits in the compression connector segment directly competing with PPC’s core product lines. For any connector manufacturer or OEM looking to enter or expand in the CATV/broadband hardware space, freedom-to-operate analysis against this portfolio remains a prerequisite.
Should your team run an FTO against PPC Broadband’s coaxial connector patents?
Any company designing, manufacturing, or importing coaxial cable connectors for broadband, CATV, or satellite distribution — particularly compression-style F-connectors — should assess exposure against US7479035B2, US10756455B2, US8172612B2, US7114990B2, and US7955126B2. This case confirms PPC Broadband is willing to litigate its portfolio aggressively. A dismissal with prejudice against one defendant provides no safe harbour for other connector suppliers.
PatSnap Eureka’s FTO Search Agent can map your connector product’s technical features against the claim scope of all five PPC patents simultaneously, flagging overlap risk and identifying prior art that could support future IPR petitions. Eureka also tracks continuation filings and related prosecution history — critical for a portfolio that evolved across multiple application years.

What this case signals for the coaxial connector IP landscape
A four-year, five-patent standoff ending in mutual dismissal carries important signals for connector hardware IP strategy.
With-prejudice exits preserve patent value for third-party enforcement
PPC Broadband’s five coaxial connector patents were never ruled invalid or not-infringed. Companies operating in the coaxial connector space — CATV, broadband infrastructure, satellite — should not treat this dismissal as clearance. Each patent remains a live enforcement risk against non-party competitors and OEM suppliers.
Cost-neutral stipulations often signal underlying commercial resolution
When parties with asymmetric litigation strength agree to split costs and dismiss with prejudice, it typically suggests a confidential settlement or licensing arrangement underpins the exit. Product designers and procurement teams sourcing competing connectors should note that the commercial terms — if any — are not publicly disclosed and may include supply or exclusivity conditions.
PPC v Perfectvision — key questions answered
PPC Broadband asserted five patents: US7479035B2, US10756455B2, US8172612B2, US7114990B2, and US7955126B2. All five cover aspects of coaxial cable connector design and construction. The accused product was PerfectVision’s SignaLoc PV6USLP coaxial cable connector.
Dismissal with prejudice means PPC Broadband cannot re-file these specific claims against PerfectVision on the same five patents. However, the patents themselves remain valid and enforceable. No court ruled on infringement or validity, so PPC retains full enforcement rights against other third-party competitors in the coaxial connector market.
The 1,399-day duration is consistent with a multi-patent infringement case that progressed through claim construction and substantial discovery before resolution. The public record does not disclose specific reasons for the timeline. Cases of this complexity in the Eastern District of Arkansas typically involve extended scheduling orders, and commercial negotiations alongside litigation often extend proceedings.
Yes. The stipulated dismissal with prejudice means no court ever adjudicated infringement of the SignaLoc PV6USLP connector. PerfectVision faces no damages award, no injunction, and no public infringement ruling. However, the dismissal also extinguished any invalidity counterclaims, so no court ruled the PPC patents invalid either.
The case provides no FTO clearance for third parties. The five PPC Broadband patents emerged with their validity and scope legally untested. Connector manufacturers, OEMs, and distributors in the CATV and broadband infrastructure segments should conduct independent FTO analysis against the full PPC portfolio before launching competing connector products.
