Case overview & background
Plain-language overview of the case: parties, accused product, patents at issue, and why the suit matters.
This patent infringement litigation, Prosperina Ventures LLC v. Service Lighting and Electrical, case number 3:26-cv-01006, is active in the Northern District of Texas, Dallas Division, and involves U.S. Patent 9,470,882, among others. The plaintiff, Prosperina Ventures LLC, is a non-practicing entity (NPE) or patent assertion entity, asserting a portfolio of six U.S. patents related to LED lighting technologies. The defendant, Service Lighting and Electrical Supplies, Inc., also known as 1000Bulbs.com, is an operating company established in 1951, operating as a lighting distributor and online light bulb store, specializing in commercial, industrial, and institutional electric lighting fixtures. The specific accused product or technology relates to LED lighting solutions offered by Service Lighting and Electrical.
U.S. Patent 9,470,882, titled "Optical sensor for detecting events," generally describes an optical sensor device configured to detect various events. The procedural posture of the case is that it was initially filed in the Northern District of Texas, Dallas Division, and then transferred to the Eastern District of Pennsylvania on January 14, 2026, following an Agreed Motion to Transfer Venue, citing improper venue in the Northern District of Texas. This transfer underscores the continuing influence of TC Heartland on patent venue decisions, even in Texas districts which had seen an increase in patent filings post-TC Heartland.
This case is notable for several reasons. It involves an NPE, Prosperina Ventures LLC, in the LED lighting sector, a common area for patent disputes. The litigation highlights the strategic importance of venue in patent cases, especially for NPEs, as the Northern District of Texas has historically been a popular forum due to its established patent litigation procedures and experienced judges. The transfer out of the Northern District of Texas indicates that even traditionally patentee-friendly districts are subject to rigorous venue scrutiny. No Inter Partes Reviews (IPRs) specifically targeting US Patent 9,470,882 were found in the provided search results.

Plaintiff representatives
Counsel of record for the plaintiff(s): attorneys, firms, and roles (lead counsel, of counsel, local counsel).
As of August 6, 2026, identifying the specific counsel of record for the plaintiff(s) in case 3:26-cv-01006 in the Texas Northern District Court, related to patent 9470882, proves challenging through general web searches. While a "Complaint analysis" snippet indicates that Prosperina Ventures LLC is likely the plaintiff, detailed public docket information listing their attorneys is not readily available.
Given the case's recent filing in 2026, it is in its early stages, and comprehensive attorney appearances might not yet be widely publicized outside of the official court docket.
Therefore, without direct access to the PACER docket for the Northern District of Texas, specific names, roles, firms, office locations, and relevant patent litigation experience for Prosperina Ventures LLC's counsel cannot be provided at this time.
Defendant representatives
Counsel of record for the defendant(s): attorneys, firms, and roles (lead counsel, of counsel, local counsel).
The previous case summary stated that the case was transferred to the Eastern District of Pennsylvania on January 14, 2026. However, some search results for case 3:26-cv-01006 indicate it remains active in the Northern District of Texas, and some suggest it was dismissed or transferred in January 2026 without adjudication on the merits. There appears to be a discrepancy in the current status and location of the case, which affects the identification of current counsel.
Based on the initial filing in the Northern District of Texas (case number 3:26-cv-01006) and a related case involving the same plaintiff (Prosperina Ventures LLC) and a different defendant (Keystone Technologies LLC) also transferred out of the Northern District of Texas (case number 3:25-cv-02886), some initial information about counsel can be inferred.
For the case Prosperina Ventures LLC v. Service Lighting and Electrical Supplies, Inc. d/b/a 1000Bulbs.com, the defendant is listed as Service Lighting and Electrical Supplies, Inc. d/b/a 1000Bulbs.com. Given the case's early stage and the venue transfer, specific counsel information for the defendant in this exact case is not readily available through general public searches at this time. However, to provide the best possible information, we can look for general patent litigation counsel for Service Lighting and Electrical or 1000Bulbs.com, or counsel appearing for defendants in similar cases brought by Prosperina Ventures LLC.
No specific counsel of record for Service Lighting and Electrical in case 3:26-cv-01006 has been found in the readily available public information. Filings are likely not yet public or are under seal, especially if the case has been transferred or is in very early stages.
To definitively identify the counsel of record for the defendant, direct access to the PACER docket for either the Northern District of Texas (original filing) or the Eastern District of Pennsylvania (post-transfer) would be necessary.
General information about Service Lighting and Electrical (1000Bulbs.com) indicates they are a lighting distributor based in Minneapolis/St. Paul, MN, and have been operating since 1951. There is no publicly available information indicating in-house patent litigation counsel for Service Lighting and Electrical.
Without direct PACER access, identifying specific defendant counsel details (name, role, firm, office, and relevant experience) for this active case is not possible at this time.
