How does the concept of structural obviousness apply to complex mixtures like zeolites?
The application of structural obviousness to complex mixtures like zeolites can be challenging and requires careful consideration. MPEP 2144.02 provides an important example: “The Court held that different crystal forms of zeolites would not have been structurally obvious one from the other because there was no chemical theory supporting such a conclusion. The known chemical…

The In re Grose case, cited in MPEP 2144.02, is significant in patent examination because it demonstrates the limitations of applying structural obviousness to complex mixtures. The MPEP states: “In re Grose, 592 F.2d 1161, 201 USPQ 57 (CCPA 1979) (Court held that different crystal forms of zeolites would not have been structurally obvious one…
