2 SANHO CORP. v.

KAIJET TECHNOLOGY INTERNATIONAL LIMITED, INC.

DYK, Circuit Judge.

Appellant Sanho Corporation (“Sanho”) appeals from a final decision of the Patent Trial and Appeal Board (“Board”) finding all challenged claims of U.S. Patent No. 10,572,429 (“the ’429 patent”) unpatentable as obvious. Each obviousness combination included U.S. Patent Application Publication No. 2018/0165053, known as Kuo. Kuo ordinarily would be prior art because its effective filing date predates the effective filing date of the ’429 patent, save for the exception in 35 U.S.C. § 102(b)(2)(B). The sole issue on appeal is the applicability of the prior art exception in that provision. It provides that “[a] disclosure shall not be prior art to a claimed invention under subsection [102](a)(2) if . . . the subject matter disclosed had, before such subject matter was effectively filed under subsection (a)(2), been publicly disclosed by the inventor.” § 102(b)(2)(B).

Sanho argues that, before Kuo’s effective filing date, the inventor of the ’429 patent “publicly disclosed” the relevant subject matter of Kuo through the private sale of a product (the HyperDrive) allegedly embodying the claimed invention. We understand the Board to have concluded that this private sale does not qualify for the exemption of section 102(b)(2)(B), and Kuo is prior art. We affirm.

BACKGROUND

The ’429 patent concerns “[a] port extension apparatus for extending ports of an end-user device,” such as a laptop computer. J.A. 928, at col. 6, ll. 46–47. The specification describes a series of ports and connections as well as a data transmission control module, which together allow devices “to connect to data ports of an end-user device.” J.A. 927, at col. 3, ll. 2–3. This allows for easier connections between , for example, a laptop computer and peripheral devices such as a printer.

SANHO CORP. v. 3 KAIJET TECHNOLOGY INTERNATIONAL LIMITED, INC.

Kaijet Technology International Limited, Inc. (“Kaijet ”) filed a petition for inter partes review challenging most claims of the ’429 patent as obvious. Each obviousness ground relied on a combination of prior art that included Kuo. The relevant portion of Kuo discloses a “control system compris[ing] a main control unit that supports USB Type-C (USB-C) interface specification, [and] an image signal processing unit electrically connected to the main control unit and adapted for receiving a display port signal.” J.A. 1362, ¶ 21 (numerals omitted). Thus, both the ’429 patent and Kuo concern docking stations for connecting multiple devices to an end user device.

In the final written decision, the Board found claims 1– 6 and 13–17 of the ’429 patent unpatentable as obvious, relying on Kuo as prior art under section 102(a)(2). Kuo’s effective filing date is December 13, 2016—before the ’429 patent’s priority date of April 27, 2017. The question was whether the patentee was correct in arguing that Kuo is not prior art by virtue of section 102(b)(2)(B) of the Patent Act because the inventor purportedly “publicly disclosed” the relevant subject matter of Kuo through the private sale of a device that incorporated the invention and predated Kuo’s effective filing date.

Specifically, Sanho contended that the inventor’s sale of the so-called HyperDrive device constituted a public disclosure by the inventor of the relevant subject matter in Kuo. Mr. Liao, the inventor of the ’429 patent, offered to sell the HyperDrive to Sanho’s owner on November 17, 2016. After obtaining a HyperDrive sample, Sanho placed an order for 15,000 HyperDrive units on December 6, 2016, that was accepted by Mr. Liao’s company, GoPod Group Ltd. (constituting an actual sale). Sanho made no showing that the sale of the HyperDrive that predated Kuo’s effective filing date was publicized in any way, or that there were any such sales other than the private sale of Hyper- Drives from the inventor to Sanho. There is also nothing in the record to indicate that the order for 15,000 4 SANHO CORP. v.

KAIJET TECHNOLOGY INTERNATIONAL LIMITED, INC.

HyperDrives was fulfilled before Kuo’s effective filing date, or what became of those devices.

The Board determined that the “Patent Owner fail[ed]

to show that the inventor publicly disclosed the subject matter of Kuo before Kuo’s effective filing date.” J.A. 39. 1 Therefore, the Board concluded that “Kuo qualifies as prior art, not excluded under § 102(b)(2)(B).” J.A. 45. The Board found all challenged claims unpatentable over combinations that all included Kuo.

This appeal followed. We have jurisdiction pursuant to 28 U.S.C. § 1295(a)(4)(A). 2

1 Before the Board, Sanho also contended that an online “Kickstarter” campaign with descriptions and photographs of the device also constituted a public disclosure. The Board rejected this argument after finding that the articles and photographs were either published after Kuo’s effective filing date or were insufficiently clear and detailed to disclose the relevant subject matter. That determination was not challenged in Sanho’s opening brief. Although Sanho suggested in its reply brief that Sanho’s owner “publicized the sale on Appellant’s Kickstarter website, publishing images, videos, and other information,” Appellant’s Reply Br. 10, any argument that the Kickstarter campaign further disclosed the subject matter of the sale is forfeited because it was not raised in the opening brief. SmithKline Beecham Corp. v. Apotex Corp., 439 F.3d 1312, 1319 (Fed. Cir. 2006).

2 Kaijet informed us that Sanho had granted it a covenant not to sue on the ’429 patent and that Kaijet “no longer has any commercial interest in the validity of this patent.” Oral Arg. 23:20–52. We consider sua sponte whether the case is moot. See Already, LLC v. Nike, Inc., 568 U.S. 85, 91 (2013). We conclude that it is not. The Board’s final written decision found claims 1–6 and 13–17

SANHO CORP. v. 5 KAIJET TECHNOLOGY INTERNATIONAL LIMITED, INC.

DISCUSSION

On appeal, Sanho argues that “[t]he Board’s failure to find that the HyperDrive sale to Sanho itself constituted a public disclosure under 35 U.S.C. § 102(b)(2)(B) was legal error.” Appellant Op. Br. 17. In response, Kaijet argues that, even if the HyperDrive embodied the relevant features of the claimed invention, the sale did not publicly disclose the relevant subject matter for purposes of section 102(b)(2)(B) because the relevant features of the claimed invention were not sufficiently publicized to render the subject matter “publicly disclosed.” 3 We consider whether a non-confidential but otherwise private sale results in an invention’s subject matter being “publicly disclosed ” for purposes of section 102(b)(2)(B).

“In 2011, Congress enacted the Leahy-Smith America Invents Act (AIA), transforming the U.S. patent system

of the ’429 patent unpatentable. Sanho still has a legally cognizable interest in the outcome of the appeal since it could assert the patent against other parties. It is still possible for us to grant relief by remanding or vacating the Board’s decision (assuming Sanho prevails). See Uniloc 2017 LLC v. Hulu, LLC, 966 F.3d 1295, 1301 (Fed. Cir. 2020).
