Avery Dennison Corp. v. Continental Datalabel, Inc., No. 10 C 2744, Slip Op. (N.D. Ill. Nov. 30, 2010) (Kennelly, J.).

Judge Kennelly granted plaintiff Avery Dennision’s ("ADC") Fed. R. Civ. P. 12(b)(6) motion to dismiss defendant Continental Datalabel’s ("CDI") inequitable conduct, Walker Process fraud and sham litigation counterclaims in this patent dispute regarding labels with a tear off liner to expose a portion of a label column for easy removal.

Inequitable Conduct

CDI alleged two bases of inequitable conduct. First, ADC allegedly intentionally failed to tell the examiner that certain limitations outlined in a series of bullet points were from a particular prior art reference. That claim filed because ADC had previously disclosed the prior art reference at issue to the examiner – once a reference is before an examiner, it cannot be found to have been withheld from the examiner. Second, ADC allegedly intentionally failed to disclose to the examiner that curling up of labels is an inherent characteristic of adhesive labels. But ADC had disclosed the inherent curling up by disclosing various prior art references regarding adhesive labels that taught the inherent curling up, combined with the examiner’s presumed experience in the art.

Walker Process Fraud Claim

Because CDI’s Walker Process claim was premised upon the alleged inequitable conduct, CDI’s Walker Process claim failed. The Court further noted that because inequitable conduct is a broader concept than Walker Process fraud, a party that fails to make its case for inequitable conduct, cannot make a Walker Process fraud claim.

Sham Litigation

CDI’s sham litigation claim was based upon allegations that ADC knew the patent was invalid based upon the Brady prior art reference, which was before the examiner, and because had ADC tested CDI’s accused labels, ADC would have realized its suit was baseless. Because the Brady reference was before the examiner, however, the Court could not find that the claim was "objectively baseless" as required for sham litigation. ADC could have reasonably believed that after the examiner considered Brady and granted ADC’s patent, ADC’s patent was in fact valid over Brady.

And ADC’s alleged failure to test the accused CDI product was not sufficient for a sham litigation claim. Sham litigation requires more than an unsuccessful suit. While CDI may eventually prove that it did not infringe, ADC’s failure to perform one test identified by CDI does "not permit the court to infer more than the mere possibility" that ADC’s suit was in bad faith.
