UNITED STATES DISTRICT COURT

FOR THE EASTERN DISTRICT OF TEXAS

MARSHALL DIVISION

COBBLESTONE WIRELESS, LLC,

Plaintiff,

v.

CELLCO PARTNERSHIP D/B/A 

VERIZON WIRELESS,

Defendant.

Case No. 2:22-cv-00478-JRG-RSP

PLAINTIFF COBBLESTONE WIRELESS, LLC’S PRELIMINARY DISCLOSURE OF 

ASSERTED CLAIMS AND INFRINGEMENT CONTENTIONS 

I. Patent Rule 3-1: Disclosure of Asserted Claims and Infringement Contentions

Pursuant to Patent Rule 3-1, Plaintiff Cobblestone Wireless, LLC submits the following

Preliminary Disclosure of Asserted Claims and Infringement Contentions. This disclosure is based 

on the information available to Cobblestone as of the date of this disclosure, and Cobblestone

reserves the right to amend this disclosure to the full extent permitted, consistent with the Court’s 

Rules and Orders.

A. Patent Rule 3-1(a): Asserted Claims

following claims (collectively, “Asserted Claims”):

(1) U.S. Patent No. 8,891,347 (“the ’347 patent”), claims 1-4, 6-12, 14-17, and 19-23;

B. Patent Rule 3-1(b): Accused Instrumentalities of which Cobblestone is aware

Cobblestone asserts that the Asserted Claims are infringed by the various instrumentalities

used, made, sold, offered for sale, or imported into the United States by Defendant, including 

certain (a) cellular base stations that support 3GPP 5G NR (“New Radio”) communications, (b) 

4G LTE cellular base stations that support handover to or from 5G NR cellular base stations, (c) 

user equipment that supports 3GPP 5G NR communications, and (d) cellular handsets, tablets, or 

smartwatches that support wifi-only automatic updates (“Accused Instrumentalities”). 

Defendant’s Accused Instrumentalities of which Cobblestone is presently aware are described in 

more detail in the accompanying preliminary infringement contention charts, Exhibits A-D.

Cobblestone reserves the right to accuse additional products from Defendant to the extent 

Cobblestone becomes aware of additional products during the discovery process. Unless otherwise 

stated, Cobblestone’s assertions of infringement apply to all variations, versions, and applications 

of each of the Accused Instrumentalities, on information and belief, that different variations, 

versions, and applications of each of the Accused Instrumentalities are substantially the same for 

purposes of infringement of the Asserted Claims.

C. Patent Rule 3-1(c): Claim Charts

Cobblestone’s analysis of Defendant’s products is based upon limited information that is 

publicly available, and based on Cobblestone’s own investigation prior to any discovery in these 

actions. Specifically, Cobblestone’s analysis is based on certain limited resources that evidence 

certain products made, sold, used, or imported into the United States by Defendants.

Cobblestone reserves the right to amend or supplement these disclosures for any of the 

following reasons:

(1) Defendant and/or third parties provide evidence relating to the Accused 

Instrumentalities;

Case 2:23-cv-00285-JRG-RSP Document 46-2 Filed 03/08/24 Page 3 of 10 PageID #: 663
3

(2) Cobblestone’s position on infringement of specific claims may depend on the claim 

constructions adopted by the Court, which has not yet occured; and

(3) Cobblestone’s investigation and analysis of Defendant’s Accused Instrumentalities is 

based upon public information and Cobblestone’s own investigations. Cobblestone

reserves the right to amend these contentions based upon discovery of non-public 

information that Cobblestone anticipates receiving during discovery.

Attached as Exhibits A-D, and incorporated herein in their entirety, are charts identifying 

where each element of the Asserted Claims are found in the Accused Instrumentalities.

Unless otherwise indicated, the information provided that corresponds to each claim 

element is considered to indicate that each claim element is found within each of the different 

variations, versions, and applications of each of the respective Accused Instrumentalities described 

above.

D. Patent Rule 3-1(d): Literal Infringement / Doctrine of Equivalents

With respect to the patents at issue, each element of each Asserted Claim is considered to 

be literally present. Cobblestone also contends that each Asserted Claim is infringed or has been 

infringed under the doctrine of equivalents in Defendant’s Accused Instrumentalities. Cobblestone

also contends that Defendant both directly and indirectly infringes the Asserted Claims. For 

example, the Accused Instrumentalities are provided by the Defendant to customers, who are 

actively encouraged and instructed (for example, through Defendant’s online instructions on its 

website and instructions, manual, or user guides that are provided with the Accused 

Instrumentalities) by the Defendant to use the Accused Instrumentalities in ways that directly 

infringe the Asserted Claims. Defendant therefore specifically intends for and induces its

customers to infringe the Asserted Claims under Section 271(b) through the customers’ normal 

and customary use of the Accused Instrumentalities. In addition, Defendant is contributorily 

Case 2:23-cv-00285-JRG-RSP Document 46-2 Filed 03/08/24 Page 4 of 10 PageID #: 664
4

infringing the Asserted Claims under Section 271(c) and/or Section 271(f) by selling, offering for 

sale, or importing the Accused Instrumentalities into the United States, which constitute a material 

part of the inventions claimed in the Asserted Claims, are especially made or adapted to infringe 

the Asserted Claims, and are otherwise not staple articles or commodities of commerce suitable 

for non-infringing use.

E. Patent Rule 3-1(e): Priority Dates

The Asserted Claims of the ’347 patent are entitled to a priority date at least as early as 

July 28, 2011, the filing date of International Application No. PCT/CN2011/077718. 

The Asserted Claims of the ’888 patent are entitled to a priority date at least as early as 

April 29, 2011, the filing date of International Application No. PCT/US2011/034470. 

The Asserted Claims of the ’361 patent are entitled to a priority date at least as early as 

August 1, 2014, the filing date of International Application No. PCT/CN2014/083578. 

The Asserted Claims of the ’196 patent are entitled to a priority date at least as early as 

August 24, 2011, the filing date of International Application No. PCT/US2011/049003. 

A diligent search continues for additional responsive information and Cobblestone reserves 

the right to supplement this response.

F. Patent Rule 3-1(f): Identification of Instrumentalities Practicing the Claimed 

Invention

At this time, Cobblestone does not identify any of its instrumentalities as practicing the 

Asserted Claims. A diligent search continues for additional responsive information and 

Cobblestone reserves the right to supplement this response.

II. Patent Rule 3-2: Document Production Accompanying Disclosure

Pursuant to Patent Rule 3-2, Cobblestone submits the following Document Production 

Accompanying Disclosure, along with an identification of the categories to which each of the 

Case 2:23-cv-00285-JRG-RSP Document 46-2 Filed 03/08/24 Page 5 of 10 PageID #: 665

documents corresponds.

F. Patent Rule 3-2(a) documents:

Cobblestone is presently unaware of any documents sufficient to evidence any discussion 

with, disclosure to, or other manner of providing to a third party, or sale of or offer to sell, the 

inventions recited in the Asserted Claims of the Asserted Patents prior to the application dates or 

priority dates for the Asserted Patents. A diligent search continues for such documents and 

Cobblestone reserves the right to supplement this response. 

G. Patent Rule 3-2(b) documents:

Cobblestone identifies the following non-privileged documents as related to evidencing 

conception and reduction to practice of each claimed invention of the Asserted Patents: 

COBB_000001-1631. A diligent search continues for additional documents and Cobblestone

reserves the right to supplement this response.

H. Patent Rule 3-2(c) documents:

Cobblestone identifies the following documents as being the file histories for the Asserted 

Patents: COBB_000081-1631.
