ViaTech Technologies, Inc. v. Microsoft Corporation

Filing 116

MEMORANDUM ORDER: Plaintiff's proposed addition to claim construction is rejected. Signed by Judge Richard G. Andrews on 6/9/2020. (nms)

IN THE UNITED STATES DISTRICT COURT
FOR THE DISTRICT OF DELAWARE

VIATECH TECHNOLOGIES, INC.,
Plaintiff,
v.

Civil Action No. 17-570-RGA

MICROSOFT CORPORATION,
Defendant.

MEMORANDUM ORDER
I directed the parties in this case to prepare a proposed order in conformity with my
recent claim construction decision. (D.I. 112). By agreement of the parties, the claim
construction order adopted my constructions in earlier litigation between the parties in ViaTech
Tech., Inc. v. Microsoft Corp., 2016 WL 3398025 (D. Del. June 14, 2016), as modified by the
Federal Circuit in ViaTech Tech., Inc. v. Microsoft Corp., 733 F. App’x 542 (Fed. Cir. 2018).
The parties now dispute whether the Federal Circuit modified my construction of the term “file.”
My first construction of “file” was “a collection of data that is treated as a unit by a file
system.” Plaintiff proposes adding a sentence, such that the term “file” means,
A collection of data that is treated as a unit by a file system. A “file” may be a
collection of files.
(D.I. 115 at 1). Plaintiff argues that this addition is necessary in light of the Federal Circuit’s
opinion. (Id. at 2). Defendant disagrees. (Id.).

Plaintiff emphasizes that the Federal Circuit stated in its opinion that it “revise[s]” the
construction. (D.I. 115 at 1). This statement appeared in the conclusion of the opinion. ViaTech,
733 F. App’x at 554. Earlier in the opinion, however, the Federal Circuit stated,
This understanding of “file” does not require changing the district court’s
construction, only its application of that construction. Thus, we uphold the district
court’s construction, but clarify that a “file” as claimed in the ’567 patent may be
a collection of files.
Id. at 550 (emphasis added). Based on this language, it appears that the construction should not
change.
I also find it helpful to compare the Federal Circuit’s discussion of the term “file” with
the term “dynamic license database.” The Court changed the construction of the latter. I had
construed it as “a database that resides in the digital content file and that is programmed to
accept modifiable licenses.” Id. at 547. The Court of Appeals construed it as “a modifiable
database in which file access control and license use information is stored and can be written.”
Id. at 550.

After reviewing my two constructions, the Court stated,

Despite changing the construction of “dynamic license database” and clarifying
the district court’s construction of “file” . . . .
Id. at 551 (emphasis added). This difference in the use of language strongly suggests that the
Court of Appeals was simply clarifying the application of the term “file” to the particular facts in
the case.
Thus, I do not think the construction has changed. I will therefore reject Plaintiff’s
proposed addition to the original construction. Of course, I have learned something about the

application of the construction from the clarification by the Court of Appeals, and do not expect
any argument contrary to what the Court of Appeals has held.
