Intex Wins Patent Challenge: Built-in Air Mattress Pump Not Unique
Share
In a recent legal decision, the U.S. Court of Appeals for the Federal Circuit (CAFC) addressed the patent claims made by Team Worldwide Corporation regarding its air mattress with a built-in pump. The court evaluated whether the invention was obvious based on prior art references.
Background:
- Team Worldwide Corporation claimed that their air mattress, which had a built-in electric pump recessed within the exterior wall of the mattress, was unique and patentable.
- Intex Recreation Corp. challenged this claim, arguing that the invention was obvious based on prior products and patents.
- Intex specifically referenced two older patents: One describing an air mattress with an externally-attached solar-powered pump and the other showing an ordinary mattress with an attached fan.
Key Issues:
- Obviousness: The main question was whether Team Worldwide's invention was obvious based on prior references. If something is considered "obvious," it's not patentable.
- Secondary Considerations: Team Worldwide presented additional evidence, such as their product's commercial success, to argue that the invention wasn't obvious. These are known as "secondary considerations."
Court Decisions:
1. The Patent Trial and Appeal Board (PTAB) initially believed the air mattress wasn't obvious. However, upon appeal, they changed their stance.
2. The CAFC agreed with the PTAB that Team Worldwide's claims were obvious and their patent was, therefore, unpatentable. They specifically noted that Team Worldwide didn't provide enough evidence to show that the success of their product was directly linked to its unique features (like the built-in pump). Instead, other non-patented features like comfort and durability might have driven the product's success.
3. The CAFC also highlighted that the older patents provided enough basis for Intex's argument that Team Worldwide's product was an obvious progression in air mattress technology.
Criticism:
Dennis Crouch, a law professor, criticized the CAFC for not providing a detailed opinion and overlooking the "secondary considerations" Team Worldwide presented.
Conclusion:
Despite Team Worldwide's efforts to prove the uniqueness of their air mattress, the courts determined it to be an obvious advancement and thus not deserving of patent protection.
