Defendant Intel Corporation (“Intel”) wishes to bring to the Court’s attention the decision 

in Grecia Estate Holdings, LLC v. Meta Platforms, Inc., No. 6:21-cv-00677-ADA, 2022 WL 

2109296, at * 6 (W.D. Tex. June 6, 2022) (“Grecia”), which is relevant to Plaintiff ParkerVision, 

Inc.’s IPR disclaimer, as raised by Intel’s Motion for Further Claim Construction. See Case Nos. 

6:20-cv-00108-ADA (the “108 Case”), Dkt. 117. Grecia, like this case, concerned a patentee’s 

IPR disclaimer and its subsequent taking of inconsistent positions regarding claim scope as 

between the IPR proceedings and the district court litigation:

To survive IPR, Grecia disclaimed any correspondence between credit card information 

and the “encrypted digital media” of the ’555 Patent. Claims 15-16 of the ’555 Patent 

require, in part, that the computer program product receive and authenticate a “membership 

verification token provided by a first user, corresponding to the encrypted digital media.” 

’555 Patent at 16:54–59. In other words, there must be some relationship between the 

“membership verification token” and the “encrypted digital media.” Grecia’s Complaint 

alleges that a Facebook Pay user’s “PayPal account or Debit and Credit Card number” is 

the claimed “membership verification token.” ECF No. 1 at 6–7. Yet, in IPR, Grecia 

asserted that credit card information could not be the “membership verification token”

because a credit card number corresponds to the credit card account and not digital media. 

Preliminary Response, Unified Patent Inc. v. Grecia, IPR2016-00789, Paper No. 5 

(P.T.A.B. June 22, 2016) at 21–22. Ultimately, Grecia seeks to benefit from claiming a 

distinction between the ’555 Patent and the DeMello reference during IPR yet refuses to 

confront the drawback of claiming the same distinction in litigation. Grecia’s allegations 

contradict prior sworn statements concerning the invention’s scope during IPR and, 

therefore, fail to “articulate why it is plausible that the accused product infringes the 

patent claim.” Bot M8, 4 F.4th at 1355. Grecia cannot possibly allege infringement on this 

ground.

Grecia, 2022 WL 2109296, at * 6 (emphases added).
