PER CURIAM.

Zhengxu He appeals a decision of the Patent Trial and Appeal Board (“Board”) affirming an examiner’s rejection of claims 1–22 of U.S. Patent Application No. 16/997,933 Case: 26-1177 Document: 30 Page: 2 Filed: 06/09/2026

2 IN RE HE

(“the ’933 application”) for obviousness. For the following reasons, we affirm.

BACKGROUND The ’933 application is directed to an automated kitchen system that transports and unloads ingredient con- tainers between storage and cooking stations. App’x 29. 1 Independent claim 1 is representative: 1. A kitchen system, comprising: a storage station comprising: a storage configured to store a plural num- ber of ingredient containers, wherein each ingredient container is used to contain or hold a food ingredient; and a container transfer apparatus configured to grip and transfer one of the ingredient containers[,] the container transfer appa- ratus comprising: a gripper mechanism comprising a support component and one or more grippers, wherein the gripper mechanism is configured to grip the ingredient container; and a motion mechanism configured to move the support component of the gripper mechanism, the motion mechanism comprising a motor or other driving mechanism; a cooking station comprising:

IN RE HE 3 a cookware configured to contain or hold a food or a food ingredient; a motion mechanism configured to move the cookware, the motion mechanism com- prising a motor or a driving mechanism; and a dispensing apparatus configured to move an ingredient container to dispense the food ingredient from one of the ingredient containers to the cookware, the dispensing apparatus comprising: a gripper mechanism comprising a support component and one or more grippers, wherein the gripper mechanism is configured to grip the ingredient container; and a motion mechanism configured to move the support component of the gripper mechanism, the motion mechanism comprising a motor or a driving mechanism; and a vehicle configured to transport one or more of the ingredient containers, wherein the vehicle is con- figured to stop at the storage station; wherein the vehicle is also configured to stop at the cooking sta- tion.

App’x 23.

4 IN RE HE

The examiner rejected claim 1 for obviousness in view of Buehler 2 and He ’660. 3 Buehler discloses an automated kitchen system that includes ingredient storage modules, cooking receptacles, and a robotic primary manipulator that retrieves food ingredients and performs cooking tasks.

The examiner found that Buehler discloses claim 1, except for: (1) a dispensing apparatus comprising a gripper mech- anism and motion mechanism; and (2) a vehicle. For these limitations, the examiner relied on He ’660, which discloses an ingredient-cart-unloading apparatus and mini vehicles that stop at storage and cooking stations. The examiner found that a person of ordinary skill in the art would have been motivated to combine these references with a reason- able expectation of success. App’x 156–57.

The Board affirmed the rejection, adopting the findings and rationale provided by the examiner. App’x 4–12.

Mr. He timely appeals. We have jurisdiction under 28 U.S.C. § 1295(a)(4)(A).

DISCUSSION We review the Board’s legal determinations de novo and its underlying factual findings for substantial evi- dence. In re Constr. Equip. Co., 665 F.3d 1254, 1255 (Fed. Cir. 2011). Whether a skilled artisan would have been motivated to combine references is a question of fact that we review for substantial evidence. Id. On appeal, Mr. He does not dispute that the combined teachings of the references disclose all elements of the claims. Instead, Mr. He argues that substantial evidence does not support the Board’s motivation-to-combine finding

Case: 26-1177 Document: 30 Page: 5 Filed: 06/09/2026

IN RE HE 5 because the offered motivations, concerning automation, do not apply to Buehler. We disagree.

The Board concluded that the examiner had articu- lated record-supported reasons for combining Buehler and He ’660. App’x 11–12. Those included He ’660’s explicit disclosures of its automated system “delivering food ingre- dients . . . in a dependable manner,” and that it “minimizes space required,” “minimizes idle time,” and “reduces labor cost.” App’x 11 (citing He ’660 at ¶¶ 2, 4–5). The examiner also explained in his rejection how incorporating He ’660’s mini vehicles and cart-unloading apparatus into Buehler would automate ingredient movement between storage and cooking stations without having to position the storage and cooking stations in a particular way. App’x 156–57. Doing so would achieve He ’660’s benefits. Id. (citing He ’660 at ¶¶ 2, 4–5). This is substantial evidence that supports the Board’s motivation-to-combine finding.

Mr. He also argues that He ’660’s “minimize[] space” rationale depends on locating storage and cooking areas re- motely, which contradicts Buehler’s teachings of locating its storage and cooking modules adjacent to form a compact unit. However, the examiner found no contradiction.

App’x 236–37. Mr. He disagrees with the examiner’s fact- finding, but he does not persuasively explain how He ’660’s benefits, of which “minizmiz[ing] space” is one among many, are exclusive to a particular configuration (i.e., lo- cating a storage module physically distant from the cooking module). Here, the Board agreed with the examiner that incorporating He ’660’s mini vehicles and unloading system would provide advantages to Buehler’s system, as just ex- plained. That finding is supported by substantial evidence and is not contradicted by Buehler’s disclosure.

Next, Mr. He argues that the examiner’s proposed mod- ification would not work in Buehler because He ’660’s un- loading mechanism requires engagement bars, which would interfere with Buehler’s rotating storage shelves.

6 IN RE HE

Mr. He’s argument is premised on He ’660’s engagement- bar mechanism being physically incorporated into Buehler.

But as the Board noted, “‘[t]he test for obviousness is not whether the features of a secondary reference may be bod- ily incorporated into the structure of the primary refer- ence,’ but rather ‘what the combined teachings of those references would have suggested.’” App’x 9 (quoting In re Keller, 642 F.2d 413, 425 (CCPA 1981)). Moreover, the ex- aminer found that “fixing a bar to an ingredient container, as taught by He [’660], would not prevent one of ordinary skill in the art from attaching a bar to Buehler’s food ingre- dient containers.” App’x 235–36. The Board agreed with the examiner, citing that finding, App’x 16, and determin- ing He ’660’s unloading apparatus to be “combinable with Buehler’s food preparation system,” App’x 10. In all, the Board found that Mr. He “ha[d] not sufficiently shown that the combination would be uniquely challenging or diffi- cult,” and that the examiner “provided sufficient motiva- tion for modifying Buehler with the teachings of He ’660.”

App’x 12. We see no error in the Board’s analysis in this regard.

Finally, Mr. He argues that the Board violated the Ad- ministrative Procedure Act (“APA”) by failing to meaning- fully respond to his arguments that (1) the motivation-to- combine finding is contradicted by Buehler and (2) the pro- posed modification would not work in Buehler. But the rec- ord shows that the Board confronted the substance of Mr. He’s contentions and explained why it found them un- persuasive. App’x 10–12 (rejecting Mr. He’s contradiction argument because the examiner provided “numerous pos- sible benefits gained from the combination”); App’x 9–12 (rejecting Mr. He’s incompatibility argument and explain- ing the test for obviousness is not bodily incorporation, but what the combined teachings would have suggested to a skilled artisan). Mr. He fails to demonstrate an APA vio- lation on this record.

CONCLUSION We have considered Mr. He’s remaining arguments and find them unpersuasive. For the foregoing reasons, we affirm the Board’s decision.

AFFIRMED COSTS No costs.
