Lockformer and PPG Industries are competitors in insulated, multi-pane glass. PPG alleged that Lockformer infringed their patent for a new kind of glass spacer and spacer frame. After close of PPG evidence, Lockformer prevailed on a motion for summary judgment because PPG failed to present any evidence that Lockformer's product did not contain an adhesive adhering to a flat metal strip. The CAFC affirmed.
Note that this opinion may not be cited as precedent.

Seachange International, Inc. v. C-Cor, Inc.

Seachange and C-Cor compete in the video-on-demand server industry. Seachange holds a patent on a distributed, fault-tolerate video distribution server network. The CAFC refused to apply the doctrine of claim differentiation because of patent prosecution history; and they interpreted the limitation "network for data communications" to only point-to-point connections. The opinion also summarizes a protest (which are fairly rare in patent prosecution). The CAFC revered the finding of infringement because Seachange stipulated that C-Cor did not literally infringe and, because of the prosecution history, applying the doctrine of equivalents would "vitiate an entire claim limitation".

About Digitized Audio Patent Case law Summaries

The digital audio files available on this site are created from the text of the published court opinion. Before creating the MP3, the text is edited (by computer and by person) to allow for easier understanding in spoken form ("listenability")
  • Most citations are not read.
  • If a citations appears contextually in a sentance, only the name of the case is read.
  • Parenthetical phrases following citations are not read.
  • Certain words frequently used in party names (LLC, Co., Inc.) are now skipped while reading.
  • Page numbers are no longer read.
  • A case summary is added.
  • Different voices are used to read the case summary, the majority opinion and any dissent.
  • Footnotes not spoken.

A short caption of each case is read first and it contains:
  • The short name of the case.
  • The name of the court.
  • The date of the decision.
  • A short summary of the case.
The resulting text is read aloud by various computer voices. Hearing the case without the forgoing information is considerably less effort for the listener. Finally, the voice is converted into an MP3 and made availble via the web and RSS. Software assists the process, but results are not guaranteed. Please check with primary sources before relying on any information found on this site.

Purdue Pharma L.P., et al. v. Endo Pharmaceuticals, Inc., et al.

The trial court found Purdue's patents unenforceable due to inequitable conduct during prosecution. Notwithstanding that the patent claims might have been otherwise enforceable, Purdue's repeated assertions of "unexpected results" that were based on insight rather than scientific evidence was material evidence of inequitable conduct and intent to deceive could be inferred from the same evidence.
