Passing the 101 Day Torch

101 Day

The 101 day has been the highlight of the Delaware patent law hearing calendar for many years now. It's an all-day no-holds-barred marathon where questions can come to any party at any time. And the best part is, you can look forward to a decision at the end of the day. It is our Super Bowl and our debutante ball all in one, where Delaware's brightest stars go to see, and be seen.

Naturally, I always attend.

I had been a bit worried that the practice would not survive Judge Stark's departure. Although other Judges have adopted the practice to some extent, Judge Stark (the progenitor of the practice) had always been the most reliable host for the event.

Updates from the Annual FBA Meeting, Including Potential Filing Deadline Change and D. Del. Local Rules Update!

Today was the Federal Bar Association's annual luncheon, an annual event where the Chief Judges give updates on the status of Delaware's District and Bankruptcy courts.

This year's event was the first in-person meeting since the start of the COVID lockdowns. It was great to see everyone again in person!

Attendance was relatively low. Some speculated that this may be due to expiring FBA memberships. My theory is that there may have been an issue with the invitation e-mail (I never received it myself, and I'm a current FBA member).

In any case, I wanted to post some highlights and interesting facts from the speakers today, as we did for the virtual event last year:

Judge Noreika Chooses a Side on IPR Estoppel: No Estoppel of Prior Art Products

IPR Estoppel Estoppel

Split

IPR estoppel can be kind of terrifying as an accused infringer in a patent action. The statute says that an accused infringer may not assert invalidity on a ground that it could have raised in the IPR; but you can't raise product prior art, so product prior art should be safe, right?

Nope. Courts have sometimes held that product prior art may still be estopped, if there is patent or written prior art that is sufficiently similar. See, e.g., Wasica Fin. GmbH v. Schrader Int’l, 432 F. Supp. 3d 448, 453 (D. Del. 2020) (holding defendant estopped from asserting product art where “all the relevant features” of the art were in a printed publication that could have been raised in an IPR).

As Judge Stark notes in Wasica, courts have gone both ways on this, with some estopping arguments based on product art where similar written or patent art could have been raised in an IPR, and others permitting those arguments.

On Friday, Judge Noreika chose a side in this split: no estoppel for prior art products ...

"Flawed Logic" Leads to Short Opinion, Negative Outcome

Claim Construction

In patent infringement cases, plaintiffs' claim construction strategy sometimes seems to boil down to "Plain meaning! Construe it later! Everything is in!", while defendants often go for "No plain meaning! Construe it now! Our thing is out!".

Note that, for defendants, it's not necessarily that everything is out of the claim. It's often that there is one specific thing from the specification that is required, and that just happens to be the one thing the defendant's product doesn't have or do.

This strategy doesn't have a great success rate for defendants, but often I feel like the attitude is that "well it's worth a shot." I'm not sure that's always true, because a really bad argument …

Court Bars Technical Expert's Testimony About Opposing Party's "Purported Litigation Misconduct, Corporate Culture, and Ethics"

When expert reports go back and forth in a patent case, it's not uncommon to see complaints from the patentee's expert along the lines of "I understand that the opposing party did not produce information regarding x, so I will instead base my opinions y."

In other words, the expert wants to keep the door open to explain to the jury that he or she would have done a particular analysis if only the other side had given them the information they needed. But, obviously, the other side may object to that testimony.

Judge Connolly addressed a situation like yesterday, and held that the expert cannot just testify to the jury about the other sides alleged …

Some Quick Takeaways from a Claim Construction Opinion Where the Court Sought Extrinsic Evidence

An embodiment of the claimed "weight-shift controlled personal hydrofoil watercraft" U.S. Patent No. 9,359,044

We don't usually write about claim construction opinions, because they tend to be fact-specific and tough to generalize to other cases.

But there were a few interesting points in a claim construction opinion issued by Judge Andrews on Friday, and I thought it was worth outlining them here:

  • While the judges are typically somewhat adverse to extrinsic evidence, Judge Andrews asked the parties to submit letters outlining "textbook[]" style definitions of the a term, "stability," and said that he found the letters helpful. He adopted the construction that "capture[d] the concept of static stability" as set forth in the textbook definitions.

The Golden Rule and Lesser Metals

Summary Judgment

It's easy to fall into the trap of separating rules into "technical" and "substantive" and on that basis to choose which must be followed and which can be safely ignored. Judge Noreika neatly illustrated how foolhardy this practice can be last week, when she issued a brief, two-sentence order denying a summary judgment motion:

WHEREAS, pursuant to the 47 Scheduling Order, a separate concise statement of facts shall be filed with any summary judgment motion; and WHEREAS, Plaintiff did not file such statement with its 194 Motion for Summary Judgment. THEREFORE, IT IS HEREBY ORDERED that the motion is DENIED for failure to comply with this Court's procedures set forth in the Scheduling Order

Court Denies Stipulation Extending Answer Deadline That Was Filed on Due Date as Untimely & Lacking Justificiation

Andrew E. Russell, June 23, 2022
Stipulation Answer

RIP, dear stipulated extension
Mr Xerty, Unsplash

Just a heads up, since this has to be one of the more common things that counsel do in cases—this week, Judge Connolly denied a stipulation extending the answer deadline as untimely and lacking a reason:

ORAL ORDER: The parties' stipulation (D.I. 16) being untimely and offering no justification for an extension, it is HEREBY DENIED. Defendant has until June 23, 2022 to answer, move, or otherwise respond to the complaint. ORDERED by Judge Colm F. Connolly on 6/21/22. (ntl) (Entered: 06/21/2022)

Wikeshire IP LLC v. TransCore, LP, C.A. No. 22-445-VAC (D. Del.).

It's not clear from the docket why it was untimely. It looks like the answer deadline was originally 4/28/2022, then it was extended by stip to 5/28, then 6/14. Then, on 6/14 (the due date), the parties filed another stipulation extending the answer deadline to 6/28.

So it looks like the Court rejected a stipulation filed on 6/14 to extend a 6/14 due date. It may be that the parties filed after the 6pm filing deadline. Or, it may be that the Court is taking the view that the stipulation must be filed early enough for the Court to "so order" it prior to the deadline—but I haven't seen that in other cases.

Either way, it's probably safest to list a justification for your stip extending the answer deadline, and to file early going forward! Of course, this can be tricky in high-volume NPE cases, where plaintiff's counsel may be unresponsive until the parties are right up against a deadline.

Should You Request Oral Argument on Your Motion in the District of Delaware?

Under the D. Del. local rule 7.1.4, a written request for oral argument is due seven days after the reply brief on a motion.

According to the rule, the Court may or may not schedule oral argument on receiving a request—and may schedule argument even if it is not requested:

Oral argument on any motion may be scheduled upon the application of a party, or sua sponte by Court order.

That leads to a common question, "Should we request oral argument on our motion?"

The short answer is: yes, if you want oral argument. The Court is going to schedule …

Looking for a Local Mediator for a District of Delaware Patent Case? It's a Short List

Since the Court suspended its mediation program, parties have noticed that the District of Delaware lacks an established pool of local mediators who are available to mediate patent cases.

As I mentioned a while back, I wanted to put together a list to help match attorneys and clients with mediators who have District of Delaware patent-case experience. I've now heard from multiple D. Del. mediators and attorneys about who people are using, and I put together this list.

Spoiler alert: It's a short list. My primary criteria were: local or nearby, active, and experienced in patent cases or patent case mediations. Even so, there are just not a ton of names, and people largely …
