APPLE, INC.

Defendant.

COMPLAINT FOR PATENT INFRINGEMENT AGAINST


APPLE, INC.

This is an action for patent infringement arising under the Patent Laws of the United States

of America, 35 U.S.C. § 1 et seq., in which Plaintiff XR Communications LLC d/b/a Vivato

Technologies (“Plaintiff” or “Vivato”) makes the following allegations against Defendant Apple,

Inc. (“Defendant”):

INTRODUCTION

1. This complaint arises from Defendant’s unlawful infringement of the following

United States patent owned by Vivato, which generally relates to wireless communications

technology: United States Patent No. 10,715,235 (the “’235 Patent”) (collectively, the “Asserted

Patent”).

2. Countless electronic devices today connect to the Internet wirelessly. Beyond just

connecting our devices together, wireless networks have become an inseparable part of our lives

in our homes, our offices, and our neighborhood coffee shops. In even our most crowded spaces,

today’s wireless technology allows all of us to communicate with each other, on our own devices,

1
Case 6:21-cv-00620 Document 1 Filed 06/16/21 Page 2 of 20

at virtually the same time. Our connected world would be unrecognizable without the ubiquity of

sophisticated wireless networking technology.

3. Just a few decades ago, wireless technology of this kind could only be found in

science fiction. The underlying science behind wireless communications can be traced back to the

development of “wireless telegraphy” in the nineteenth century. Guglielmo Marconi is credited

with developing the first practical radio, and in 1896, Guglielmo Marconi was awarded British

patent 12039, Improvements in transmitting electrical impulses and signals and in apparatus

there-for, the first patent to issue for a Herzian wave-based wireless telegraphic system. Marconi

would go on to win the Nobel Prize in Physics in 1909 for his contributions to the field.

4. One of Marconi’s preeminent contemporaries was Dr. Karl Ferdinand Braun, who

shared the 1909 Nobel Prize in Physics with Marconi. In his Nobel lecture dated December 11,

1909, Braun explained that he was inspired to work on wireless technology by Marconi’s own

experiments. Braun had observed that the signal strength in Marconi’s radio was limited beyond a

certain distance, and wondered why increasing the voltage on Marconi’s radio did not result in a

stronger transmission at greater distances. Braun thus dedicated himself to developing wireless

devices with a stronger, more effective transmission capability.

5. In 1905, Braun invented the first phased array antenna. This phased array antenna

featured three antennas carefully positioned relative to one another with a specific phase

relationship so that the radio waves output from each antenna could add together to increase

radiation in a desired direction. This design allowed Braun’s phased array antenna to transmit a

directed signal.

6. Building on the fundamental breakthrough that radio transmissions can be directed

according to a specific radiation pattern through the use of a phased array antenna, directed

2
Case 6:21-cv-00620 Document 1 Filed 06/16/21 Page 3 of 20

wireless communication technology has developed many applications over the years. Braun’s

invention of the phased array antenna led to the development of radar, smart antennas, and,

eventually, to a technology known as “MIMO,” or “multiple-input, multiple-output,” which would

ultimately allow a single radio channel to receive and transmit multiple data signals

simultaneously. Along the way, engineers have worked tirelessly to overcome limitations and

roadblocks directed wireless communication technology.

7. At the beginning of the twenty-first century, the vast majority of wireless networks

still did not yet take advantage of directed wireless communications. Instead, “omnidirectional”

access points were ubiquitous. Omnidirectional access points transmit radio waves uniformly

around the access point in every direction and do not steer the signal in particular directions.

Omnidirectional antennas access points do typically achieve 360 degrees of coverage around the

access point, but with a reduced coverage distance. Omnidirectional access points also lack

sophisticated approaches to overcome certain types of interference in the environment. As only

one example, the presence of solid obstructions, such as a concrete wall, ceiling, or pillar, can limit

signal penetration. As another example, interference arises when radio waves are reflected,

refracted, or diffracted based on obstacles present between the transmitter and receiver. The

multiple paths that radio waves can travel between the transmitter and receiver often result in signal

interference that decreases performance, and omnidirectional access points lack advanced

solutions to overcome these “multipath” effects.

8. Moving from omnidirectional networks to modern networks has required an

additional series of advancements that harness the capabilities of directed wireless technology.

These advancements range from conceiving various ways to steer and modify radiation patterns,

to enhancing the transmission signal power in a desired direction, to suppressing radiation in

3
Case 6:21-cv-00620 Document 1 Filed 06/16/21 Page 4 of 20

undesired directions, to minimizing signal “noise,” and then applying these new approaches into

communications networks with multiple, heterogenous transmitters and receivers.

9. Harnessing the capabilities of directed wireless technology resulted in a significant

leap forward in the signal strength, reliability, concurrent users, and/or data transmission capability

of a wireless network. One of the fundamental building blocks of this latest transition was the

development of improvements to MIMO and “beamforming,” which are the subject matter of

patents in this infringement action. The patents in this action resulted from the investment of tens

of millions of dollars and years of tireless effort by a group of engineers who built a technology

company slightly ahead of its time. Their patented innovations laid the groundwork for today’s

networks, and are infringed by Defendant’s accused products.

Case 6:21-cv-00620 Document 1 Filed 06/16/21 Page 17 of 20

; id. Clause 22.3.11.2:

27. Defendant also has been and is now knowingly and intentionally inducing

infringement of at least claim 8 of the ’235 Patent in violation of 35 U.S.C. § 271(b). Through at

least the filing and service of this Complaint, Defendant has had knowledge of the ’235 Patent and

the infringing nature of the ’235 Accused Products.

28. Despite this knowledge of the ’235 Patent, Defendant continues to actively

encourage and instruct its customers and end users (for example, through user manuals and online

instruction materials on its website) to use the ’235 Accused Products in ways that directly infringe

the ’235 Patent. For example, Defendant’s websites provided, and continues to provide,

instructions for using the ’235 Accused Products on wireless communications systems, to utilize

their 802.11ac and/or 802.11ax beamforming and/or MU-MIMO functionalities. Defendant does

so knowing and intending that its customers and end users will commit these infringing acts.

Defendant also continue to make, use, offer for sale, sell, and/or import the ’235 Accused Products,

despite its knowledge of the ’235 Patent, thereby specifically intending for and inducing its

customers to infringe the ’235 Patent through the customers’ normal and customary use of the ’235

Accused Products. Defendant also knows or was willfully blind that its actions would induce direct

17
Case 6:21-cv-00620 Document 1 Filed 06/16/21 Page 18 of 20

infringement by others and intended that its actions would induce direct infringement by others.

Accordingly, a reasonable inference is that Defendant specifically intended for others, such as its

customers, to directly infringe one or more claims of Vivato’s ’235 Patent in the United States

because Defendants had knowledge of the ’235 Patent and actively induced others (e.g., its

customers) to directly infringe the ’235 Patent.

29. Defendants also contributorily infringe under 35 U.S.C. § 271(c) by making, using,

selling, offering to sell, and/or importing the ’235 Accused Products, knowing they constitute a

material part of the invention, are especially made or adapted for use in infringing, and that they

are not staple articles of commerce capable of substantial non-infringing use.

30. By making, using, offering for sale, selling and/or importing into the United States

the ’235 Accused Products, Defendants have injured Vivato and is liable for infringement of

the ’235 Patent pursuant to 35 U.S.C. § 271.

31. Defendant also infringes numerous additional claims of the ’235 Patent, including

Claim 12, for example, directly and through inducing infringement, for similar reasons as

explained above with respect to Claim 8.

32. Vivato’s ’235 Patent is valid and enforceable.

33. Vivato has complied with 35 U.S.C. § 287 where applicable (i.e., as to non-method

claims) because there are no unmarked patented articles subject to a duty to mark.

34. As a result of Defendant’s infringement of the ’235 Patent, Defendant has damaged

Vivato, and Vivato is entitled to monetary damages in an amount to be determined at trial that is

adequate to compensate for Defendant’s infringement, but in no event less than a reasonable

royalty for the use made of the invention by Defendant, together with interest and costs as fixed

by the Court.

18
Case 6:21-cv-00620 Document 1 Filed 06/16/21 Page 19 of 20

35. Defendant’s infringing activities have injured and will continue to injure Vivato,

unless and until this Court enters an injunction prohibiting further infringement of the ’235 Patent,

and, specifically, enjoining further manufacture, use, sale, importation, and/or offers for sale that

come within the scope of the patent claims.

PRAYER FOR RELIEF

WHEREFORE, Vivato respectfully requests that this Court enter:

a. A judgment in favor of Vivato that Defendant has infringed, either literally and/or

under the doctrine of equivalents the ’235 patent;

b. A permanent injunction prohibiting Defendant from further acts of infringement of

the ’235 patent;

c. A judgment and order requiring Defendant to pay Vivato its damages, costs,

expenses, and pre-judgment and post-judgment interest for Defendant’s infringement of the ’235

patent;

d. A judgment and order requiring Defendant to provide an accounting and to pay

supplemental damages to Vivato, including without limitation, pre-judgment and post-judgment

interest and an award of an ongoing royalty for Defendant’s post-judgment infringement in an

amount according to proof;

e. A judgment and order finding that this is an exceptional case within the meaning

of 35 U.S.C. § 285 and awarding to Vivato its reasonable attorneys’ fees and costs against

Defendant, and enhanced damages pursuant to 35 U.S.C. § 284; and

f. Any and all other relief as the Court may deem appropriate and just under the

circumstances.
