Se-Kure Controls, Inc. v. Vanguard Prods. Group Inc., No. 02 C 3767, 2008 WL 169054 (N.D. Ill. Jan. 17, 2008) (Cox, Mag. J.).*

Judge Cox denied plaintiff’s motion to exclude defendants’ patent law expert witness, but placed limits on the expert’s testimony. The Court held that a patent expert’s testimony could aid the Court’s understanding of Patent Office procedures and of what would have been material to a reasonable patent examiner. But the patent law expert was not allowed to testify as to any legal conclusions. And the testimony would be given outside the jury’s presence to avoid any prejudice. Because the Court decides inequitable conduct, there was no need for the jury to hear the expert’s testimony.

Se-Kure Controls, Inc. v. Diam USA, Inc., No. 06 C 4857, 2008 WL 169029 (N.D. Ill. Jan. 17, 2008) (Cox, Mag. J.).*

Judge Cox granted in part a motion to compel discovery regarding defendant’s advice of counsel defense. The Court ordered defendants to product a technical witness that provided opinion counsel information because opinion counsel was unable to remember the substance of conversations between the two.

The Court also ordered production of communications between opinion counsel and trial counsel related to the patent in suit. These communications were within the scope of defendant’s waiver, even though a deposition of trial counsel would not have been allowed.

The Court did not allow plaintiff to take any additional fact depositions. Plaintiff argued it had waited to take certain fact depositions because the witnesses were expected to be Fed. R. Civ. P. 30(b)(6) designers regarding defendants’ willfulness defense. But the Court did not allow the deposition because fact discovery was closed and because plaintiff had deposed other witnesses on the same topics. 

The most exciting part of this opinion, however, was its form, not its substance – Judge Cox used footnotes for cites. While this format is infinitely more readable and has many prominent advocates – Brian Garner, the (new) legal writer,  Wayne Scheiss and me (perhaps not the most prominent but I am an advocate of footnote citation) – it is a bold move in the typically conservative realm of judicial writing. At least one other Northern District Judge, Chief Judge Holderman, has used footnote citation. If you are aware of other examples, let me know. 

Thank you Judge Cox.

Vanguard Prods. Group, Inc. v. Diam USA, Inc., No. 05 C 1323, Slip Op. (N.D. Ill. May 16, 2007) (Bucklo, J.).*

Judge Bucklo granted plaintiffs summary judgment of infringement and denied defendants summary judgment of invalidity.  The Court first construed the two claim terms at issue -- "electrically coupled" and "via the modular connector."  In both cases, the Court adopted the plaintiffs' construction after a detailed review of the intrinsic and extrinsic evidence.  Because neither term was in the original application or appears in the specification, the intrinsic evidence focused on the use of the terms within the claims.  Defendants also attempted to use claim language from a parent application to support their constructions, but the Court held that the prosecution of a term in a parent application generally does not limit different terms in its progeny.  In the instant case, the Court found that the parent application had used the broader term "electrical connection" instead of "electrically coupled" which weighed against defendants' construction.  Having ruled in plaintiffs' favor on the claim construction, the Court held that defendants' products infringed the asserted claims of plaintiffs' patents.  And the Court held that defendants' asserted prior art did not anticipate plaintiffs' patents.

Se-Kure Controls, Inc. v. Vanguard Prods. Group, Inc., No. 02 C 3767, 2007 WL 781250 (N.D. Ill. Mar. 12, 2007) (Cole, Mag. J.).

Judge Cole denied plaintiff's motion to exclude plaintiff's document as a Rule 37 sanction for defendants' failure to identify its potential reliance upon the document and the person who created it.  During the discovery process, plaintiff produced a "Contact Report" listing calls made by one of its sales employees (who eventually left plaintiff's employ).  Defendants sought to rely upon the document as part of their 35 USC Section 102(b) on sale bar defense (similar to the issue in the Court's last opinion in this case).  Plaintiff argued that defendants should not be allowed to rely upon the document because:  1) defendants failed to identify the Contact Report in their responses to plaintiff's invalidity interrogatory; and 2) defendants did not identify the Contact Report's author (plaintiff's former employee) in their Rule 26 disclosures.  As with plaintiff's previous Rule 37 arguments, the Court denied them because defendants made plaintiff aware of the documents during discovery.  The Court noted that plaintiff was arguing defendants should be barred from relying on a document plaintiff produced for failure to identify plaintiff's document to plaintiff.  The Court was not swayed by defendants' failure to identify the Contact Report's author because he was plaintiff's ex-employee and because he had passed away and, therefore, would not be brought as a witness.  Finally, the Court explained that while a party has a right to be apprised of an opposing party's evidence, but not necessarily the weight or significance the opposing party places on that evidence.

Se-Kure Controls, Inc. v. Vanguard Prods. Group, Inc., No. 02 C 3767, 2007 WL 781253 (N.D. Ill. Mar. 7, 2007) (Cole, Mag. J.).

Judge Cole denied plaintiff's motion to exclude two defense witnesses as a Rule 37 sanction for failing to properly disclose the witnesses.  During the discovery process, defendants identified two witnesses, through declarations signed by the witnesses, as having knowledge of a 35 USC Section 102(b) on sale bar.  Although defendants provided plaintiff the witnesses' declarations and otherwise identified the witnesses to plaintiff, defendants failed to add the witnesses to their respective Rule 26 disclosures and they failed to supplement their respective responses to plaintiff's interrogatory seeking details of all of defendants' invalidity defenses.  Plaintiff argued that these failures led to plaintiff's decision not to depose the witnesses and that defendants' should be barred from relying upon the witnesses for failure to update their Rule 26 disclosures and interrogatory responses.  The Court, however, held that while nondisclosure would generally result in exclusion, exclusion was not warranted in the instant case because defendants did disclose the witnesses in writing.  As a result, "[s]upplementation would have availed nothing required by the [Federal] Rules and was thus unnecessary."
