Markman Briefing 10 Terms

Late last summer, we posted about an interesting order from Judge Noreika rejecting the parties' claim construction chart for including too many terms. As Judge Noreika released a similar order just last week, I though it might be interesting to examine how firm the 10-term limit has been in the months since that first order.

The answer is "very." in the 20-some Markman orders Judge Noreika has issued since that first one, she has never once construed more than 10 terms. 4 times, she has rejected a claim construction chart for including more than 10 (14, 13, 13, and 17 terms were included in those rejected charts). In each case, she has …

Judge Connolly Offers an Insight on Sufficiency of Contentions

Andrew E. Russell, May 3, 2021
Infringement Contentions Contentions

As we've mentioned, Judge Connolly uses a different system of patent contentions than the other District of Delaware judges. The other judges generally use the system set forth in the Default Standard, while Judge Connolly's approach is modeled after the more restrictive method used in the Northern District of California.

Because he uses a unique system, parties often wonder just how much (or how little) is needed to offer sufficient contentions in Judge Connolly's view.

Judge Connolly offered some insight on that point today, when he overruled a patentee's objections to an accused infringer's invalidity contentions. Here is one of the contentions at issue:

Claims 1, 2, and 4 of the ’489 patent are invalid under 35 U.S.C. § …

Indefiniteness Dooms Computer Bag Claims

Andrew E. Russell, May 3, 2021
Markman Briefing Indefiniteness

Judge Andrews today released a claim construction regarding several computer bag claims. Six of the claims at issue included elements regarding orientation of the opening in a computer bag:

“[pouch] opening[s] [is/are] . . . oriented in a direction substantially parallel to the planar surface”

U.S. Pat. No. 8,567,578
U.S. Pat. No. 8,567,578 U.S. Pat. No. 8,567,578

He found the claims indefinite because a POSITA would not understand the "orientation" of a bag opening, and the specification and prosecution history offered no hints:

At oral argument, [defendant] Victorinox contended that it is impossible to choose between two plausible views as to how to identify the orientation of the pouch opening; the “planar view” articulated by Victorinox and the direction pointing out of the pouch …

Judge Connolly Institutes New Summary Judgment Procedures to Deter Meritless Motions

Andrew E. Russell, April 30, 2021
SJ Litigation

In a new standing order today, Judge Connolly announced a new procedure for SJ motions in patent cases. Going forward, he will require parties in all patent cases (current and future) to rank their summary judgment motions, and if any motion is denied, he will generally deny all lower-ranked motions as well:

1. A party that files more than one summary judgment motion shall number each motion to make clear the order the party wishes the Court to consider the motions in question. The first motion the party wishes the Court to consider shall be designated #1, the second motion shall be designated #2, and so on.
2. The Court will review the party’s summary judgment motions in the …

Prior Expert Testimony from IPR Inadmissible in District Court Action

Trial Motion in Limine

In another ruling from the In Re ChanBond litigation as it approaches trial, Judge Andrews today issued an in-depth opinion granting a motion in limine to exclude reference to prior expert testimony from a related IPR proceeding, on the grounds that the testimony is hearsay.

Plaintiff sought to admit the material as former testimony under FRE 804(b)(1), because it is helpful to its infringement case. The rule requires, however, that the former testimony was offered against the parties' predecessor who had "an opportunity and similar motive to develop it."

Here, Judge Andrews found that an IPR petitioner's motive in developing expert testimony to show invalidity is different from a defendant's motive developing its non-infringement position:

D. Del. Permits FRAND Antitrust Claim to Proceed

A different kind of Sherman

This week, Chief Judge Stark ruled on a motion to dismiss a FRAND-related antitrust claim brought by Lenovo against InterDigital relating to 3G/4G phone standards.

According to the Court, InterDigital contracted with the European Telecommunications Standards Institute (ETSI) to license its patents at FRAND rates, and its patents were incorporated into the 3G/4G standards. The ETSI requires patentees to license their patents at FRAND rates to avoid anti-trust concerns.

Lenovo's antitrust claims allege that InterDigital, by demanding higher-than-FRAND rates, has obtained an unlawful monopoly power over the 3G/4G standards. Lenovo also alleges that InterDigital defrauded ETSI during the standards development process:

Lenovo allege[s] …

Final Score Card for the March 12th § 101 Day Hearing

Andrew E. Russell, March 22, 2021
§ 101 Days § 101

On Friday, Chief Judge Stark released his opinion summarizing his bench rulings from his most recent Section 101 day. This is how the patents fared:

Content Square v. Quantum Metric, Inc., C.A. No. 20-832-LPS (D. Del.)

In the first case, Content Square, the Court invalidated the claims of 2 of the 5 asserted patents.

The invalidated patents related to "heat map patents," which relate to displaying heat maps of web browsing data. These include U.S. Patent Nos. 10,063,645 and 10,079,737.

The third patent, which was not invalidated, related to "creating multiple versions of a website to determine users' preferences." Interestingly, the Court held …

Judge Andrews: Claim Not Indefinite, Despite Possible Drafting Error

Indefiniteness Claim Construction

Claim construction opinions tend to be highly fact-specific, so even though they can be critically important to the parties in a case, we don't always post about them on this blog.

Judge Andrews issued an interesting claim construction opinion today, however, which addressed indefiniteness due to a potential drafting error in a claim.

The opinion involved claim language for a mechanical device:

. . . wherein the . . . assembly comprises a housing comprising the syringe and the stirring motor . . .

Defendants argued indefiniteness in light of the dual use of "comprising," because a person of skill in the art cannot determine a …

Initial Contentions in Delaware Patent Cases: A Primer

Jeff Castellano, Feb. 23, 2021
Default Standard KB

In the vast majority of patent case in Delaware, the parties are required to serve initial patent disclosures in the form of infringement and invalidity contentions (separate from the contentions they might otherwise serve as part of written discovery). These initial contentions set the stage for fact discovery, claim construction, expert reports, and (in some cases) settlement.

Initial patent disclosures were formalized in this District to some degree by the Court's creation of the Default Standard for Discovery nearly a decade ago. The Default Standard established a staged set of initial disclosures that was eventually adopted by most of the Judges here.

Chief Judge Stark Suggests Requirement for Copyright Infringement Contentions, Similar to Patent Infringement Contentions

Infringement Contentions Copyright

In May 2020, West Publishing and Thomson Reuters filed a copyright action against ROSS Intelligence LLC, alleging that ROSS (through a third party) scraped content from WestLaw to start its own Artificial-Intelligence-based legal research platform. (ROSS has since ceased operations but persists solely to litigate this case.)

Down the line, I imagine the case may raise some interesting questions about AI and copyright. For example, what are the copyright implications of ROSS's use of Westlaw's copyrighted compilation of otherwise public domain materials to train an AI? Isn't that fair use (talk about transformative!)? If not, what are the damages? And so on.

For now, ROSS has moved to dismiss on the ground that West failed to …
