Background
Priceline.com, founded by Jay Walker and backed by Walker Digital, held U.S. Patent No. 5,794,207 on a “method and apparatus for a cryptographically assisted commercial network system designed to facilitate buyer-driven conditional purchase offers” — commonly known as the “name-your-own-price” or reverse auction patent for travel services. The patent covered a method in which buyers named a price they were willing to pay for airline tickets, hotel rooms, or rental cars, and sellers (airlines, hotels) could accept or reject those offers anonymously.
In 2000, Priceline.com sued Microsoft’s Expedia travel site, alleging that Expedia’s “Fare Matcher” and related pricing tools infringed the patent. The case was one of the highest-profile e-commerce patent disputes of the early internet era, involving a patent that had issued during the post-State Street Bank window when business method patents were being granted broadly.
The Legal Issues and Resolution
The litigation raised fundamental questions about the scope of the Priceline reverse auction patent: how broadly did the claim language cover competing approaches to buyer-driven pricing? What constituted a “conditional purchase offer” and what variations on the auction mechanism fell within or outside the claims? The case settled in 2001 before any final adjudication of validity or infringement — a common outcome in major e-commerce patent disputes of the era, where the uncertainty of litigation outcomes encouraged early resolution.
The settlement illustrated the leverage that broad internet business method patents provided in the early 2000s: even absent a final invalidity or infringement determination, the threat of litigation from patents on fundamental e-commerce mechanisms like reverse auctions could compel competitors to reach licensing arrangements or settlements rather than contest validity through expensive litigation to judgment.
Key Takeaways
- The Priceline reverse auction patent was a paradigmatic example of post-State Street Bank business method patents on internet commerce mechanisms — broadly claiming a fundamental pricing method (buyer-driven conditional offers) that might today face serious § 101 abstract idea challenges under Alice.
- E-commerce patent disputes of the early 2000s frequently settled before reaching final adjudication, giving broad business method patents significant licensing leverage in an era before IPR and Alice provided efficient mechanisms for challenging such patents.
- The name-your-own-price business model and patent illustrated the competitive and legal dynamics of internet business method patent protection: early internet companies with novel business models could often obtain broad patents that competitors found difficult to design around without infringing or litigating.
- Patents like Priceline’s reverse auction patent — which claimed a fundamental internet pricing mechanism — would face significant § 101 vulnerability under the current Alice framework, where concepts like “reverse auctions” and “buyer-driven pricing” are likely abstract ideas that cannot be patented merely through internet implementation.
Why It Matters
Priceline.com’s reverse auction patent and the litigation it spawned represent an important chapter in the history of e-commerce patent law — illustrating both the commercial power of early internet business model patents and the legal environment that made them possible. The post-State Street Bank era enabled companies like Priceline, Amazon (one-click purchasing), and others to obtain broad patents on internet-specific business mechanisms that provided competitive advantages through exclusive rights to fundamental e-commerce approaches.
Looking back from the post-Alice era, these patents illustrate how dramatically the § 101 landscape changed: patents on fundamental internet pricing mechanisms, auction formats, and commercial transaction methods that were routinely issued in 1997-2010 would face serious invalidity challenges under Alice’s abstract idea framework. The Priceline era is thus a historical baseline for understanding the transformation of software and business method patent eligibility that Alice wrought — and for evaluating the ongoing commercial and legal significance of the thousands of pre-Alice business method patents that remain in force.
