Can a rejected US design patent be salvaged? Lawyer Shen Jinlong discusses the response path for design patents, and these three types of misconceptions are the most common

First of all, the conclusion is that the vast majority of US design patent rejections can be saved

Can. The proportion of Office Actions (OA) issued by USPTO examiners that truly constitute "insurmountable" defects is not high. The rejection of design applications mostly focuses on three types of issues: drawing quality, novelty judgment, and the combination of obviousness. As long as a response that meets the requirements of 37 C.F.R. § 1.121 is submitted within the deadline, along with modifications to the drawings or submission of claims amendments, a significant portion of the applications can be authorized. In practice, we usually advise clients not to give up in a hurry and to have their lawyers read the entire OA document before deciding on a plan.

The response period is only 3 months; it can be extended, but it will cost money.

The USPTO's OA response period for design applications is a relatively short statutory period of 3 months from the date of mailing, not the automatically extendable 3 months for ordinary invention patents. If you want to delay, you can apply for an extension, but you need to pay an extension of time fee, which will be gradually increased by 1 month, 2 months, and 3 months. Failure to respond within the deadline will be considered as abandoned. Many customers who encounter it for the first time may think that "it can be done slowly like a trademark", but they miss the deadline and can only go through the request to revoke process, which requires additional payment and explanation of unintentional delay. Don't bet on time.

Misconception 1: Thinking that changing the drawings can pass

Drawing issues are the most frequent reasons for rejection in exterior design OA, commonly including unclear lines, improper shading, mixed use of dashed and solid lines, and inconsistencies between different views of the same design. The examiner relied on the clarity requirement of 35 USC § 112. Modifying drawings is not impossible, but the boundary is very narrow: adding new matter is absolutely not allowed, and any modifications beyond the original public scope will be rejected. We have handled many cases where the client redrawn the 3D drawing themselves, but the scale did not match the original view, resulting in a new § 112 issue. Before modifying the drawings, it is necessary to compare each line in the original application document.

Misconception 2: Treating novelty rejection as the final conclusion

The examiner's citation of prior patents or public publications for novelty rejection (35 USC § 102) does not mean that your design is rejected. The key is to compare whether the files belong to the 'identical design'. The novelty judgment of exterior design is based on the overall visual impression, not the specific parts. If there are substantial differences in the overall appearance, proportion, and decorative elements of the compared files, they can be argued reasonably. We usually recommend customers to provide side by side comparison charts, listing the differences one by one, which is much more effective than simply writing textual arguments. When encountering rejection in § 102, let me ask first: Is the document cited by the examiner really "the same"?

Misconception 3: Neglecting the lethality of obvious combinations

More troublesome than novelty is the rejection of obviousness, usually based on 35 USC § 103, where the examiner combines two to three prior designs and argues that the designer in this field has a "motivation" to make your design. This type of rejection response is the most difficult, as examiners often only give one sentence: 'Combination is a conventional design technique'. The key to refutation lies in whether the overall visual effect of the combination produces new decorative effects, and whether there is a lack of "primary reference". In practice, we will start from the overall impression of the design and argue that the combination does not form the same visual theme. Many customers underestimate § 103 for the first time and think it's just as easy to refute as § 102, but it's not.

The most easily overlooked program details in the response

In addition to physical reasons, there are also several pitfalls in the program. The response document must be signed by a registered practitioner, and responses submitted by foreign applicants themselves are often returned due to format inconsistencies; The official fee standards for small entities and micro entities are different, and incorrect declaration may result in retroactive payment of fees; If there are both rejection and objection in OA, they should be responded to separately, and only half of the response will be considered incomplete. In addition, after the response is submitted, the examiner may issue a Final Office Action, and the available paths are to continue the response, submit a continuation application, or appeal to the Patent Trial and Appeal Board (PTAB). The cost difference between these three paths is significant, and which one to choose depends on your business layout.

Do you want to find a lawyer? Look at these three signals

Not every OA must hire a lawyer. If the rejection is only a formal issue, such as a mistake in a certain figure in the instruction manual, it can be corrected by oneself. But as long as the following three situations occur, it is recommended to hand them over to a professional team: first, the reason for rejection involves the obviousness of § 103; Secondly, the examiner cited multiple comparative documents; Thirdly, your product has already been launched in the United States, and the authorization period directly affects rights protection and platform complaints. Cross border e-commerce sellers should be particularly aware that patent complaints on platforms such as Amazon are sensitive to patent status, as a pending application and an authorized patent can have completely different outcomes. For the overall layout of cross-border intellectual property, you can refer to the overseas intellectual property information we have compiled.

How to determine the response strategy, first look at the business purpose

The same OA can have both radical and conservative responses. The radical strategy is to argue extensively and insist on the scope of the original claims; The conservative strategy is to moderately narrow the scope of protection in exchange for quick authorization. Which one to choose depends on whether you are applying for this design to prevent plagiarism, for listing, or for financing due diligence. We usually advise clients to set out their business schedule first and then determine the pace of their response. When it comes to the two legal jurisdictions of the United States and the European Union, the differences in examination standards between the two sides also need to be considered. The overall impression judgment of design by the European Union Intellectual Property Office (EUIPO) is not completely consistent with that of the United States Patent and Trademark Office (USPTO). For the issue of multi jurisdictional collaboration, please refer toUS and EU trademark and patent filing page.If you have layout needs outside the United States, there are corresponding explanations in intellectual property legal services in other countries.

The application volume is still increasing in 2026, and the response window is more valuable

In the past two years, the number of design applications submitted by Chinese applicants to USPTO has continued to rise, and the examination cycle has also been extended accordingly. In practice, it usually takes 14 to 21 months from the application to the first OA for a design, and then several months to wait for authorization after receiving a response. This means that if you have a new product to go global in 2026, the timing of patent authorization must be reversed in advance. The quality of the response directly determines whether you want to go through the second and third procedures, each of which means additional official and legal fees. Taking OA seriously is much cheaper than remedying it afterwards.
