Tech Energy Products Sued Over Valve Patent Infringement
Texas oilfield equipment suppliers should review product designs to ensure compliance with recent patent litigation.
Updated on Oct. 13, 2026 in Oil and Gas

Tech Energy Products LLC has filed a patent infringement lawsuit against Worldwide Oilfield Machine Inc. in the US District Court for the Western District of Texas. The litigation centers on pressure-balanced adjustable choke technology used in oil and gas well operations.
Why it matters
Patent disputes in the oilfield services sector can create significant uncertainty regarding equipment procurement and operational standards. Operators must assess whether their existing flow control assets align with ongoing intellectual property enforcement actions.
The lawsuit targets pressure-balanced adjustable chokes utilized for fluid pressure reduction, centering on the claims of US Patent No. 10,156,106 B2. The scope of affected units and potential financial liability remains currently unknown.
The players
Tech Energy Products LLC
An intellectual property holder and manufacturer operating within the energy sector.
Worldwide Oilfield Machine Inc.
A developer and manufacturer of oilfield equipment, including valves and pressure control systems.
Worldwide Oilfield Machine Valves & Controls Inc.
A subsidiary specialized in the production of valve and pressure control technology for the oil and gas industry.
The details
The lawsuit alleges that Worldwide Oilfield Machine Inc. and its subsidiary, Worldwide Oilfield Machine Valves & Controls Inc., incorporated protected valve technology into their pressure-balanced adjustable chokes. These devices serve a critical role in controlling the pressure of fluids flowing from active oil and gas wells. If the court finds the patent claims valid and infringed, the defendants may be required to modify their product designs or halt sales of the contested valve components.

Market Landscape
This case sits within the standard legal framework of the U.S. Patent Act, which governs intellectual property enforceability in the oilfield sector. It serves as a reminder of the competitive risks associated with valve and pressure-control technology development.
Operators currently using pressure-balanced adjustable chokes from the named defendants should verify their supply chain continuity and review existing service agreements. Ensure your legal counsel monitors the court docket for any injunctions that could disrupt equipment availability.
The takeaway
Intellectual property enforcement can result in sudden supply chain gaps if specific equipment is pulled from the market. Keep a list of alternative vendors for critical pressure-control valves to avoid delays should this litigation lead to an injunction against the defendants.
