Rule of Law:
A patent claim that recites both an apparatus (a system) and a method of using that apparatus within a single claim is indefinite under 35 U.S.C. § 112, paragraph 2, and is therefore invalid.
Facts:
- IPXL Holdings, L.L.C. ('IPXL') is the owner of U.S. Patent No. 6,149,055 ('the '055 patent'), titled 'Electronic Fund Transfer or Transaction System.'
- The '055 patent describes a system that stores user-defined information and displays it on a single screen, allowing a user to execute a financial transaction in fewer steps.
- Amazon.com, Inc. ('Amazon') developed and uses a '1-click system' for online purchases.
- Amazon's 1-click system allows customers to store information, such as credit card numbers and shipping addresses, to place an order without having to re-enter that information for subsequent purchases.
Procedural Posture:
- IPXL Holdings, L.L.C. filed a lawsuit against Amazon.com, Inc. in the U.S. District Court for the Eastern District of Virginia, alleging infringement of its '055 patent.
- The district court granted summary judgment in favor of Amazon.
- The district court ruled that Amazon's system did not infringe the patent and that all asserted claims of the '055 patent were invalid.
- Specifically, the district court found claims 1, 2, 9, and 15 were invalid as anticipated, and claim 25 was invalid for indefiniteness.
- The district court also found the case to be 'exceptional' and awarded attorney fees and costs to Amazon.
- IPXL appealed the district court's judgment on invalidity, noninfringement, and the award of attorney fees to the U.S. Court of Appeals for the Federal Circuit.

Issue:
Is a patent claim that recites both an apparatus and a method of using that apparatus indefinite under 35 U.S.C. § 112, paragraph 2?
Opinions:
Majority - Clevenger, Circuit Judge.
Yes. A patent claim that attempts to claim both an apparatus and a method for using that apparatus is indefinite and therefore invalid. The court, facing an issue of first impression, adopted the reasoning of the PTO's Board of Patent Appeals and Interferences from Ex parte Lyell. The court reasoned that combining two distinct statutory classes of invention (apparatus and method) into a single claim creates ambiguity. This ambiguity prevents competitors from being reasonably apprised of the claim's scope, as it is unclear whether infringement occurs when the apparatus is made or sold, or only when a user performs the method steps. Such a claim fails to 'particularly point out and distinctly claim' the invention as required by 35 U.S.C. § 112, paragraph 2. Claim 25 of the '055 patent recites 'The system of claim 2...' (an apparatus) and then describes how 'the user uses the input means...' (a method), which renders the claim invalid for indefiniteness.
Analysis:
This decision establishes a bright-line rule in the Federal Circuit that mixing apparatus and method limitations within a single patent claim renders it invalid for indefiniteness. It formally elevates the long-standing position of the PTO's Board of Appeals into binding Federal Circuit precedent, providing clarity for patent prosecutors and litigators. This holding underscores the importance of disciplined claim drafting, requiring that apparatus claims and method claims remain distinct to be valid. The ruling simplifies infringement analysis for future cases by eliminating the ambiguity of hybrid claims, which made it difficult for manufacturers to determine if making a device, without a user performing the method steps, constituted infringement.
