`
`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 Speir Technologies Limited (“Plaintiff” or
`
`“Speir”) makes the following allegations against Defendant Apple Inc. (“Defendant” or “Apple”):
`
`INTRODUCTION

`
`On information and belief, Defendant Apple Inc. is a publicly traded corporation
`
`organized under the laws of the State of California, with its principal place of business at One
`
`Apple Park Way, Cupertino, CA 95014. Apple may be served with process through its registered
`

`
`JURISDICTION AND VENUE
`
`4.
`
`This action arises under the patent laws of the United States, Title 35 of the United
`
`States Code. This Court has original subject matter jurisdiction pursuant to 28 U.S.C. §§ 1331 and
`
`1338(a).
`
`5.
`
`This Court has personal jurisdiction over Apple in this action because Apple has
`
`committed acts within this District giving rise to this action and has established minimum contacts
`
`with this forum such that the exercise of jurisdiction over Apple would not offend traditional
`
`notions of fair play and substantial justice. Apple, directly and through subsidiaries or
`
`intermediaries, has committed and continues to commit acts of infringement in this District by,
`
`among other things, making, using, importing, offering to sell, and selling products that infringe
`
`the Asserted Patents. Apple has not contested personal jurisdiction in this District in prior cases.
`
`See, e.g., Scramoge Tech. Ltd. v. Apple Inc., No.6:21-cv-00579-ADA, Dkt. No. 31, ¶ 5 (W.D. Tex.

`
`Venue is proper in this District under 28 U.S.C. §§ 1391 and 1400(b). Venue is
`
`proper in this District under 28 U.S.C. §§ 1391 and 1400(b). Apple is registered to do business in
`
`Texas, and upon information and belief, Apple has transacted business in this District and have
`
`committed acts of direct and indirect infringement in this District by, among other things, making,
`
`using, offering to sell, selling, and importing products that infringe the Asserted Patents. Apple

`
`APPLE’S INFRINGEMENT

`9.
`
`The allegations provided below are exemplary and without prejudice to Plaintiff’s
`
`infringement contentions provided pursuant to the Court’s scheduling order and local rules.
`
`Plaintiff’s claim construction contentions regarding the meaning and scope of the claim terms will
`
`be provided under the Court’s scheduling order and local rules. As detailed below, each element
`
`of at least one claim of each of the Asserted Patents is literally present in the accused products. To
`
`the extent that any element is not literally present, each such element is present under the doctrine
`
`of equivalents. Plaintiff’s analysis below should not be taken as an admission that the preamble is
`
`limiting. While publicly available information is cited below, Plaintiff may rely on other forms of
`
`evidence to prove infringement, including evidence that is solely in the possession of Apple and/or
`
`third parties.
`
`10.
`
`The accused products include at least the following products, as well as products
`
`with reasonably similar functionality. Identification of the accused products will be provided in
`
`plaintiff’s infringement contentions pursuant to the Court’s scheduling order and local rules.
`
`Apple imports into the United States, uses, makes, offers for sale, and sells in the United States
`
`the following products and infringes the asserted claims of the patents-in-suit (the “Accused
`
`Products”):
`
`•
`
`’780 Patent Accused Products: iPhone 12, iPhone 12 Mini, iPhone 12 Pro, iPhone 12
`

`
`COUNT I
`
`INFRINGEMENT OF U.S. PATENT NO. 8,345,780
`
`11.
`
`Plaintiff realleges and incorporates by reference the foregoing paragraphs as if fully
`
`set forth herein.
`
`12.
`
`Apple has been and is now directly infringing the ’780 Patent, literally and/or under
`
`the doctrine of equivalents, in violation of 35 U.S.C. § 271(a), including by making, using, selling,
`
`and/or offering for sale in the United States or importing into the United States infringing products,
`
`including at least the Accused Products identified above. The Accused Products satisfy all of the
`
`claim limitations of one or more claims of the ’780 Patent, including but not limited to claim 9.
`
`13.
`
`Claim 9 of the ’780 Patent recites “[a] wireless communications device operable to
`
`communicate with an other wireless communications device via a wireless communications link
`
`having at least one settable link characteristic.” To the extent the preamble is limiting, the Accused
`
`Products each comprise a wireless communications device operable to communicate with an other
`
`wireless communications device via a wireless communications link having at least one settable
`
`link characteristic. For example, the Accused Products are configured to communicate with base
`
`stations using 5G cellular technology:

`
`14.
`
`Claim 9 of the ’780 Patent recites that the “wireless communications device”
`
`comprises “an orthogonal frequency-division multiplexing (OFDM) wireless transceiver.” The
`
`Accused Products each comprise an orthogonal frequency-division multiplexing (OFDM) wireless
`
`transceiver. For example, 5G uses OFDM in both the uplink and the downlink:

`
`Claim 9 of the ’780 Patent recites “a controller coupled to said wireless transceiver
`
`and configured to store short term and long term historical characteristics of interference.” The
`
`Accused Products each comprise a controller coupled to said wireless transceiver and configured
`
`to store short term and long term historical characteristics of interference. For example, the
`
`controllers in the Accused Products are configured to store short term and long term historical
`
`characteristics of interference:

`
`Many transmission features in modern radio-access technologies are based on the availability of more or less
`detailed knowledge about different characteristics ofthe radio channel over whicha signalis tobe transmitted.
`This may range from rough knowledge ofthe radio-channel path loss for transmit-power adjustmentto detailed
`knowledge about the channel amplitude and phase in the time, frequency, and/or spatial domain. Many transmis-
`sion features will also benefit from knowledge about the interference level experienced atthe receiver side.
`Such knowledge about different channel characteristics can be acquired in different ways and by measure-
`ments on either the transmitter side or receiver side ofaradiolink Asanexample, knowledge about downlink
`channel characteristics can be acquired by meansofdevice measurements. The acquired information could then
`be reported tothe network for the setting of different transmission parametersfor subsequent downlink transmis-

`8.2: Downlink Measurements and Reporting
`
`An NR device can be configured to carry out different measurements, im most cases with corresponding reporting
`to the network. In general, such a configuration ofa measurement and corresponding reporting are done by means
`ofa report configuration, in the 3GPP specifications [15] referred to as a CSI-ReportConyig.-
`Each resource configuration describes/indicates:
`
`- The specific quantity or set ofquantities to be reported;
`«The downlink resource(s) on which measurements should be carried out in order to derive the quantity or
`quantities to be reported;
`«How the actual reportingis tobe carried out, for example, when the reportingis to be done and what uplink

`
`Each Reporting Setting CS/-ReportConfig is associated with a single downlink BWP (indicated by higher layer

`
`The time domain behavior of the CS/-ReportConjig 1s indicated by the higher layer parameter reportConjigType and
`can be set to ‘aperiodic’, 'semiPersistentOnPUCCH, 'semiPersistentOnPUSCH’, or ‘periodic’. For periodic and
`semiPersistentOnPUCCH,senuPersistentOnPUSCH CSI reporting, the configured periodicity and slot offset applies in
`the numerology ofthe UL BWP in which the CSI report is configured to be transmutted on. The higher layer parameter

`indicates the reporting granularity in the frequency domain, including the CSI reporting band and if PMI/CQIreporting
`is wideband or sub-band. The timeRestrictionPorChannelMdeasurements parameter in CS/-ReportConjig can be

`
`wideband interference, self interference, and narrowband interference based upon comparing at
`
`least one characteristic of a current received signal with the short term and long term historical
