`
`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,

`
`

`

`
`
`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
`
`Exhibit 1004
`Page 02 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
`
`Exhibit 1004
`Page 03 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.

`
`Each ’235 Accused Product performs a method for use in a wireless
`
`communications system, the method comprising receiving a first signal transmission from a remote
`
`station via a first antenna element of an antenna and a second signal transmission from the remote
`
`station via a second antenna element of the antenna simultaneously, wherein the first signal
`
`transmission and the second signal transmission comprise electromagnetic signals comprising one
`
`or more transmission peaks and one or more transmission nulls. For example, as with each ’235
`
`Accused Product, the Apple iPhone XS Max receives a first signal transmission from a remote
`
`station, such as a Wi-Fi Access Point, via a first antenna element of an antenna and a second signal
`
`transmission from the remote station via a second antenna element of the antenna simultaneously,
`
`such as when the Apple iPhone XS Max receives first and second signals with its first and second
`
`antenna elements that contain training fields of a null data packet used for MU-MIMO sounding
`
`and channel estimation procedures. See, e.g., Compare iPhone models, iPhone XS Max (Wireless

`
`Each ’235 Accused Product performs a method for use in a wireless
`
`communications system, the method comprising determining a set of weighting values based on
`
`the first signal information and the second signal information, wherein the set of weighting values
`
`is configured to be used by the remote station to construct one or more beam-formed transmission

`
`
`signals, and transmitting to the remote station a third signal comprising content based on the set of
`
`weighting values. For example, as with each ’235 Accused Product, the Apple iPhone XS Max
`
`determines a set of weighting values based on the first signal information and the second signal
`
`information, wherein the set of weighting values is configured to be used by the remote station to
`
`construct one or more beam-formed transmission signals, and transmits to the remote station a
`
`third signal comprising content based on the set of weighting values, by determining the
`
`parameters of the beamforming feedback matrix, which include weighting values configured to be
`
`used by the remote station (e.g., a Wi-Fi access point) to construct one or more beamformed
`
`transmission signals, and transmitting to the remote station (e.g., a Wi-Fi access point) a signal
`
`that includes the beamforming feedback matrix. See, e.g., Compare iPhone models, iPhone XS
`
`Max (Wireless technology includes “Wi-Fi 5 (802.11ac) with MIMO”; Chip includes “A12 Bionic
`
`chip; Second-generation Neural Engine”). See, e.g., Apple iPad Pro 12.9-in Data Sheet (“802.11ax

`Wi-Fi 6; simultaneous dual band (2.4 GHz and 5GHz; HT80 with MIMO”; Chip includes “Apple
`
`M1 chip, 8-core CPU with 4 performance cores and 4 efficiency cores, 8-core GPU, 16-core Neural
`
`Engine”). See, e.g., IEEE 802.11ac Standard Clause 9.31.5.1 (“Transmit beamforming and DL-
`
`MU-MIMO require knowledge of the channel state to compute a steering matrix that is applied to
`
`the transmitted signal to optimize reception at one or more receivers. The STA transmitting using
`
`the steering matrix is called the VHT beamformer and a STA for which reception is optimized is
`
`called a VHT beamformee. An explicit feedback mechanism is used where the VHT beamformee
`
`directly measures the channel from the training symbols transmitted by the VHT beamformer and
`
`sends back a transformed estimate of the channel state to the VHT beamformer. The VHT
`
`beamformer then uses this estimate, perhaps combining estimates from multiple VHT
`
`beamformees, to derive the steering matrix.”); See, e.g., 802.11ac Standard Clause 9.31.5.2 (“A

`
`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
`
`Exhibit 1004
`Page 17 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.
`
`33.
`
`Vivato’s ’235 Patent is valid and enforceable.
`
`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
`
