Defining Patent Infringement: Making vs. Repair in United Wire Ltd v. Screen Repair Services
Introduction
The case of United Wire Limited v. Screen Repair Services (Scotland) Limited and Another and Others ([2000] UKHL 42) represents a pivotal moment in UK patent law, particularly concerning the boundaries between repair and making of patented products. United Wire Limited, the patentee, specialized in manufacturing vibratory sifting machine screens used in the offshore oil-drilling industry. Screen Repair Services (Scotland) Limited sought to recondition and resell these screens by refurbishing the patented frames and meshes without the consent of United Wire. The core legal issue revolved around whether such reconditioning constituted patent infringement by making the patented product or was merely an allowable repair.
Summary of the Judgment
The House of Lords upheld the decision of the Court of Appeal, affirming that Screen Repair Services' actions amounted to the making of the patented product, thereby infringing United Wire's patent rights under section 60 of the Patents Act 1977. The Defendants argued that they were only repairing the screens, which should not constitute infringement. However, the Lords clarified that the critical question was whether the Defendants had made the patented product, irrespective of whether their actions were classified as repairs. Consequently, reconditioning the frames and reassembling the screens to function as per the patented design was deemed infringement.
Analysis
Precedents Cited
The judgment extensively referenced several key precedents to substantiate its reasoning:
- Betts v. Willmott (1871): Established the concept of an implied licence, allowing purchasers to use or resell patented products.
- Solar Thomson Engineering Co. Ltd v. Barton (1977): Addressed the distinction between repair and making, initially supporting the idea of an implied licence to repair.
- Sirdar Rubber Co. Ltd. v. Wallington, Weston & Co. (1907): Clarified the boundary between repair and manufacturing.
These cases collectively influenced the Lords to delineate clearly between making and repairing, rejecting the notion that repair actions could implicitly grant rights akin to manufacturing under patent law.
Legal Reasoning
The Lords emphasized that the determination of patent infringement hinges on whether the defendant has "made" the patented product, as defined by section 60(1)(a) of the Patents Act 1977. They reasoned that repairing a product and making a new one are legally distinct actions. While repairs may involve restoring a product to its original state, making a product entails creating a new instance of the patented invention. In this case, the Defendants' process of stripping down the frames and reassembling them with new meshes effectively constituted making the patented screen assembly anew, rather than merely repairing an existing one.
The House of Lords also rejected the reliance on implied licences in this context, deeming them superfluous for actions amounting to making. They clarified that implied licences or exhaustion doctrines do not extend to the manufacture of patented products without consent.
Impact
This judgment has significant implications for patent enforcement and aftermarket services. It delineates a clear boundary that merely repairing a patented product does not grant the right to manufacture similar products. Companies engaging in reconditioning or refurbishing patented items must ensure that their activities do not cross into making as defined by patent law. This decision reinforces the proprietary rights of patentees, ensuring that they retain control over the manufacturing of their inventions even in secondary markets.
Complex Concepts Simplified
Implied Licence
An implied licence occurs when the patentee does not explicitly grant permission but allows certain uses of the patented product through their actions, such as selling the product. However, this does not extend to manufacturing new instances of the patented invention.
Exhaustion Doctrine
Also known as the "first sale doctrine," it holds that once a patented product is sold, the patentee's control over the product is exhausted, allowing the purchaser to use or resell it. This doctrine does not, however, permit the purchaser to manufacture new patented products.
Section 60 of the Patents Act 1977
This section outlines the exclusive rights granted to a patentee, including the rights to make, dispose of, offer to dispose of, use, import, or keep the patented product. Infringement occurs if these rights are exercised without consent.
Conclusion
The House of Lords' decision in United Wire Ltd v. Screen Repair Services underscores the importance of distinguishing between making and repairing in the realm of patent law. By affirming that reconditioning a patented product constitutes making the patented invention, the judgment reinforces the exclusive rights of patentees to control the manufacturing of their inventions. This clarity aids in safeguarding patent rights and provides a definitive stance for future cases involving similar disputes. Overall, the judgment fortifies the legal framework that balances innovation incentives with fair market practices.
