§101 Profile

6,128,415 claims a device profile to rid digital image distortion. The courts found it patent ineligible for being an abstraction. The CAFC (2013-1600): "For all categories except process claims, the eligible subject matter must exist in some physical or tangible form." The noose tightens on patenting software.

Essential

The U.S. courts have done their best to limit patent scope and validity within the past decade, in reponse to corporate complaint. The sensible formula of writing a specification in problem-solution form turned into a formula for obviousness without evidence after KSR. In X2Y Attenuators v. ITC (2013-1340), the CAFC affirms another trick: terming a feature as "essential" in the disclosure limits any claim to that feature to the embodiment specifically disclosed. X2Y also created a corrupt precedent, in allowing any claim limitations in earlier applications to leak into a later CIP without claim construction, to argue invalidity. With the courts corrupted to mega-corporate interests, the broken U.S. patent system continues to squash invention by inventors and small companies with caprice.
