We wrote last week about an accused infringer's attempt to secure a TRO to force the patentee to undo their efforts to get the infringer's product de-listed from Amazon.

Judge Stark swiftly ruled on the TRO, ultimately denying it for failure to show a likelihood of success on the merits:

ORAL ORDER: Having considered all the briefing and other relevant materials . . . and having heard short oral argument yesterday, IT IS HEREBY ORDERED that [accused infringer] EIS's motion for a temporary restraining order and preliminary injunction (D.I. 139) is DENIED. EIS has not shown a likelihood of success on the merits. EIS's noninfringement argument (D.I. 140 at 7−9) turns on construction of the …

Here's one I haven't seen before. In EIS, Inc. v. Intihealth GER GmbH, C.A. No. 19-1227-LPS (D. Del.), the counterclaim-defendant filed a motion for a TRO to force the patentee defendant to withdraw infringement notices it provided to Amazon.com regarding the counterclaim-defendant's products, and to force them to request that Amazon restore the product's ranking and reviews on the site:

Plaintiff EIS Inc. (“EIS”) respectfully moves the Court to grant a temporary restraining order to enjoin Defendants, requiring them to withdraw their patent infringement notice(s) to Amazon that reference EIS’s “Satisfyer” products, and ordering that the withdrawal shall request that Amazon restore EIS’s product listings with the same rankings and customer reviews …

We mentioned earlier this week that "plain and ordinary meaning" (sometimes shortened as "plain meaning" or "ordinary meaning") is the default in claim construction. But what is it?

As the Federal Circuit has said, plain and ordinary meaning is the meaning of a phrase to a person of skill in the art:

The ordinary and customary meaning of a claim term is the meaning that the term would have to a person of ordinary skill in the art in question at the time of the invention, i.e., as of the effective filing date of the patent application. . . . The inquiry into how a person of ordinary skill in the art understands a claim term provides an …

At a claim construction hearing earlier this month, Chief Judge Connolly noted some concerns with parties who offer "plain and ordinary meaning" constructions without explaining what that meaning is:

THE COURT: And going forward, Mr. Oakes, Mr. Russell, I am tempted to say the next time I get this situation [where] one side, the plaintiff[,] says, oh, plain and ordinary meaning and offers no alternative definition and all it does is criticize the defendant['s construction], which there's some actual[ly] support for, [then] I don't hold a hearing. I'm just going with the defendant. I was really tempted to do that in this case. So get the word out.

Volterra Semiconductor LLC v. Monolithic Power Systems, Inc., C.A. No. 19-2240-CFC-SRF, at 22:22-23:7 (D. Del. Nov. 12, 2021) (transcript).

Chief Judge Connolly also pointed out a "new trend" of parties ...

All six challenged patents survived Judge Stark's most recent § 101 Day, held on November 22, 2021. The six patents were spread across three cases. Continuing his usual practice, Judge Stark ruled from the bench after hearing argument in all three cases, and then issued a written order (see below) incorporating the transcript of his bench ruling and the formal orders on the pending motions.

In the first case, considering Step One of the Alice framework, Judge Stark found that the challenged patent was not directed to the abstract idea posited by the defendant ("an algorithmic method of manipulating and combining genetic sequence data using an [intermediate] data set") and instead "enables the identification of mutations with positional accuracy in a computationally tractable manner," solving a prior art problem - notably, that sequence assembly providing for accurate detection of variants was often computationally intractable for high-throughput analysis.

Judge Stark denied the motion to dismiss based on the Step One analysis.

In the second case, Judge Stark took the somewhat unusual path of deciding Step Two of the Alice test before Step One. He explained:

The Federal Circuit has employed a similar approach and resolved 101 issues at Step Two in several of its cases, ...

At a claim construction hearing the week before last, Chief Judge Connolly discussed the pitfalls of a party proposing "plain meaning" as a construction without specifying what the plain meaning is, and how that may just end up deferring disputes until later in the case. We'll have a post about that once the transcript is available.

In the meantime, I thought it was interesting that Judge Andrews this month declined to adopt opposing proposed constructions from the parties in an action, and construed the term as "plain and ordinary meaning":

Plaintiffs expert Dr. Robert Ruffolo asserts that a person of ordinary skill in the art would have understood the term "pharmaceutical batch" to incorporate [a] regulatory definition . . . …

This week, Chief Judge Connolly denied a joint request for leave to present an early SJ motion on damages in a patent action. The parties hoped that resolution of the motion would set the stage for settlement.

Judge Connolly reiterated his rule that he will not permit early SJ motions unless they are going to be the only SJ motions, while also commenting on his case load:

As a general rule, I do not allow for an early summary judgment motion unless the resolution of the motion would be case dispositive and the party seeking to file the motion agrees that it cannot file any other summary judgment motions. In light of my case load, which approaches 600 civil cases …

"Moon flask with Aesthetic bird motif" The Met

Judge Stark today issued an opinion holding five claims across four patents indefinite, based on two terms: "aesthetic" and "similar to a light house." The Court held that both terms indefinite because they are subjective. As to "aesthetic," the Court rejected an argument that "aesthetic" merely differentiated between artistic and functional aspects of light:

The Court . . . agrees with [accused infringer] HeathCo that "aesthetic" is subjective and, accordingly, the claim term is indefinite. [Patentee] Vaxcel insists "aesthetic" is not subjective because it relates to the "philosophy" or "science" of "beauty and ugliness," not to whether something is pleasing or displeasing. . . . This is unpersuasive, in part …

Back in September we wrote about how Judge Andrews rejected an expert who relied on a 50/50 starting point to show damages in a patent case. We noted at the time that the defendant had moved to strike any follow-up theory by the plaintiff, and it wasn't clear that the Court had ruled on it before trial began.

Now we know what actually happened. Yesterday, the Court released its opinion on the motion to strike. In its opinion, the Court explained that after the plaintiff lost its damages expert, the plaintiff tried to "cobble together" a damages theory from various facts on the Friday before trial. The Court struck that new theory:

[Plaintiff] NexStep …

Most patent litigators are familiar with means-plus-function claims, which are defined by 35 U.S.C. § 112(f) (previously § 112 ¶ 6). They allow a patentee to write a claim limitation as a "means" or "step" for performing a function, which is performed by the corresponding structure (or material, or acts) within the specification.

Section 112 ¶ 6 can be a gold mine for accused infringers. If they successfully argue that a claim element falls under § 112 ¶ 6, they can then argue invalidity based on a lack of corresponding structure, or they can argue non-infringement if there is structure but their products lack any equivalent. Patentees usually don't want to construe their claims as § 112 …
