Talbert Fuel Systems Patents Co. v. Unocal Corp.
The CAFC found that, even accepting the patentee's view that gasoline
fractionation does not readily achieve or require an exact endpoint, the
prosecution history does not permit a claim scope that departs significantly
from the stated temperature range. The patentee had limited the claim scope
to avoid the prior art, and the alleged infringe product had an endpoint
higher than the patentee's claims but lower than the prior art.
