Bloom Engineering Company, Inc. v. North American Manufacturing Company, Inc.

How courts have described this case

Verbatim parenthetical descriptions written by other courts when citing this decision. Ranked by citation-network relevance.

• holding that original claims were not substantially identical to reissue claims because “[t]he amendment [after reexamination] narrowed the claims to exclude an injected gas stream that includes combustion air, and to require a separate combustion air stream.”
• noting that “the scope of the claims must be the same after reissue, not that the same words must be used”
• “Unless a claim granted or confirmed upon reexamination is identical to an original claim, the patent can not be enforced against infringing activity that occurred before issuance of the reexamination certifi- cate.”
