certificate was issued canceling all the claims. Crustless peanut butter and jelly sandwich entitled "Sealed crustless sandwich" was issued in 1999 to applicants Len Kretchman and David Gesked. The patent claimed an improved crustless peanut butter and jelly sandwich, which could be mass-produced and sold in stores. The patent was licensed to Smuckers, which then introduced the Uncrustables brand of frozen no-crust sandwiches. Smuckers invested about $20 million to build a factory in Scottsville, Kentucky to produce the product. Its annual sales in 2005 were $US 60 million. To enforce the patent, Smuckers filed a patent infringement lawsuit against alleged infringer, Albie's Foods. Albie's Foods responded by filing a request for ex parte reexamination. The examiner rejected the claims in the patent, and the rejection had been appealed to the BPAI. The BPAI rejected the claims, and in 2006, the USPTO issued a Notice of Intent to Issue a Reexam Certificate, which was subsequently issued in 2007 cancelling all claims of the patent. In 2008 the patent lapsed due to the patent owner not paying the renewal fee.
