imo. 4 Years of effort by DM was not entered into without considering this possible outcome. They likely have an alternative strategy, especially considering that the language of the claim construction was so vague.

Trial is still an option and by the following you see this likely is a tool to push the parties toward settlement. EDIG still can take this the distance, and will the infringers risk that outcome?

Consider this:

NORTH CAROLINA LAW REVIEW

[Vol. 89

Supreme Court recognized that issue preclusion would apply

generally to patent law in

Blonder-Tongue Laboratories, Inc. v.

University of Illinois Foundation

14

but never addressed the specific

application of the doctrine. While the Federal Circuit did

acknowledge that “local issue preclusion law” would apply generally

in the context of patent infringement claims,

15 its opinion in

RF

Delaware, Inc. v. Pacific Keystone Technologies, Inc.

16

is only

marginally helpful to practitioners.

17

Based on the discrepancies that arose between the various

district courts, much scholarship has focused on issue preclusion in

patent claim construction, which the Supreme Court recognized in

Markman

but left to decide another day.18

This scholarly conversation

stemming from

Markman

has presented several arguments for why

issue preclusion should not apply to claim construction. The primary

argument has been over the question of whether a claim construction

order constitutes a final judgment—a required element in many

circuits before a trial court may apply issue preclusion.

19

Arguments

that a claim construction order is not a final judgment point out that a

losing party lacks the ability to immediately appeal an adverse

decision

20

and that trial judges are allowed to revisit claim

construction at later stages in the litigation.

21

Other scholars point to

the dispositive nature of a claim construction order

22

and its tendency

to push the parties toward settlement, which does not result in a final

judgment on the merits.

23

Alternatively, a party may lose some of its

arguments on claim construction but still prevail at trial on its

infringement claims, thereby leaving no opportunity to appeal the

claim construction to the Federal Circuit.

24

In neither of these last two

scenarios could the losing party on claim construction appeal that

decision.
