The Federal Circuit reversed an ITC decision that invalidated US Synthetic's composition of matter claims for being abstract ideas. This ruling establishes critical limits on patent ineligibility under Section 101, determining that polycrystalline diamond compacts used in drill bits are indeed patent eligible. The court criticized the ITC’s expansive interpretation of abstract ideas that could threaten the patentability of similar claims. This decision highlights ongoing debates over patent eligibility, particularly surrounding composition of matter claims and their functional definitions.
This case marks an important limitation on the seemingly ever-expanding realm of patent ineligibility under Section 101.
US Synthetic's patent claims covering polycrystalline diamond compacts (PDCs) used in drill bits are patent eligible, rejecting the ITC's determination.
