Lawyer Shen Jinlong explains how Shenzhen enterprises should prepare for the process of US invention patent application from technical disclosure to OA response. Poor technical disclosure can slow down the entire process

Conclusion first: Utility Patent applications in the United States, from technical disclosure to authorization, mostly hold Shenzhen companies back not because of the technology itself, but because the disclosure is written too thin. If the disclosure document does not clearly explain the invention points, alternative solutions, and experimental data, the US Patent and Trademark Office (USPTO) examiner will repeatedly challenge the claims, and a non Final Office Action response will take 3 months, two to three rounds, and 12 to 18 months. Writing the disclosure as an engineering document is the most time-saving step for the Shenzhen hardware team.

If the technical disclosure is written as a product manual, the examiner cannot understand the invention points

I have seen too many disclosure documents submitted by Shenzhen customers, which are full of product parameters, structural diagrams, and BOM tables, but there is not a single sentence that clearly states' where am I new compared to existing technology '. Among the three levels of the US Patent Law, 35 USC § 101, § 102, and § 103, the most common killer is the obviousness rejection in § 103, which precisely targets the "point of invention". If the disclosure document does not clearly state the distinguishing technical features and the unexpected technical effects it brings, the agent can only rely on guessing. The scope of the independent claims written out is either too narrow and bypassed by competitors, or too broad and rejected by the examiner with a combination of two comparative documents.

In practice, we usually recommend that clients include a separate section in the disclosure document, answering three questions: what is the closest existing technology, where is the difference between my solution and it, and what measurable effects does this difference bring. Even a number like 'reducing power consumption from 1.2W to 0.8W' is much more useful than 'better performance'. This part of the content is written solidly, and there will only be ammunition for modification and debate in the subsequent OA response.

The attached drawings are not illustrations, they are the second life of the claims

The tolerance for drawings in US patent applications is different from that in China. 37 C.F.R. § 1.84 has strict requirements for the margins, lines, and annotations of drawings. More importantly, features that are not written in the specification or illustrated in the drawings will be rejected by the examiner as "new matter" if further modifications are made to add claims. The consumer electronics team in Shenzhen often changes the structure to the final version before thinking about applying, and the disclosure book still contains the old version explosion diagram. The agent writes the rights items according to the old diagram, and it is too late to supplement them after the product is finalized.

Our approach is to have the R&D team provide the final version of the structure diagram, process diagram, and sequence diagram together during the disclosure stage, with corresponding figures and text descriptions. Spending an extra two to three days on this step can save at least one round of OA in the future.

Priority for 12 months, not letting you wait until the 12th month to move

The priority period given by the Paris Convention is 12 months, and many Shenzhen companies use it as a buffer period, first applying domestically and then slowly considering whether the United States should do it. The problem is that the United States has a "First Inventor to File" system and there is an absolute novelty bar under 35 USC § 102 (b) - once your own product is publicly sold or used in the United States, it loses its novelty after more than one year. From the day cross-border e-commerce sellers listed on Amazon, the clock began to run.

We generally recommend that the preparation of materials for the US case be initiated within 3 months after the domestic application is submitted, and that the disclosure document, drawings, and inventor's declaration (Oath/Declaration) be collected in one go. If you really need to wait for market feedback, make a decision at least 9 months in advance, leaving a buffer for translation and filming. For the PCT pathway, the 30 month deadline for entering the US national phase cannot be crossed.

IDS is not optional, missing it may turn patents into waste paper

The United States has a unique system called Information Disclosure Statement (IDS). Applicants and agents have an obligation to proactively submit known comparative documents that may affect patentability to USPTO. This is not just going through the motions - if deemed to have engaged in 'unfair conduct', the entire patent may be deemed unenforceable. A common pitfall for Shenzhen enterprises is that the R&D team knows about a certain paper or competitor, but fails to inform the agent, and is eventually dug up by the opposing lawyer in a lawsuit.

Our experience is to add a column called 'known existing technology' in the disclosure book, allowing inventors to list all the literature, competitor models, and exhibition materials they can recall. I'm not sure if it's relevant, so I'd rather submit more. The examiner will screen it themselves. The cost of this job is very low, but it saves the big trouble of future rights protection. For more details on cross-border applications, you can refer to intellectual property legal services in other countries.

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

The Non Final Office Action issued by USPTO has a response period of 3 months from the date of issuance, which can be extended, but requires an Extension of Time Fee, which is charged in steps of 1 to 5 months and increases with the number of months of delay. After the Final Office Action, the options are narrower: either submit a Request for Continued Examination (RCE) and pay within 2 months, or appeal to the Patent Trial and Appeal Board (PTAB), or give up.

Many customers panic when encountering OA for the first time and feel that the reviewer has completely denied it. In fact, it is common for US examiners to reject applications. In the first round of OA, the combination of rejections in § 103 accounted for a considerable proportion. The key is the response strategy: whether to modify the claims to narrow down the scope, use experimental data to argue for non obviousness, or cite technical teachings that the examiner did not consider. We usually recommend that customers bring in the R&D team within one week after receiving the OA, as many points of contention require the inventor to provide additional explanations or test data, which cannot be gathered temporarily.

Track One can speed up, but not all cases are worth it

USPTO's Track One priority review program can compress the issuance time of initial review opinions to approximately 4 to 6 months, at the cost of additional priority review fees (currently in the thousands of dollars range for large entities, with exemptions for small and micro entities). Shenzhen companies often ask if they want to buy this acceleration. My judgment is that if the product lifecycle is short, counterfeit products have already appeared in the market, or financing due diligence requires patent authorization to support the facade, Track One is worth it; If it is a basic material or process patent with a long protection period and difficult infringement evidence collection, following the ordinary process is more relaxed, and leaving the budget for subsequent OA responses and overseas layout is more cost-effective.

Another reminder is that Track One only accelerates the review process without lowering the review standards. If the disclosure is poorly written, acceleration will only make you receive rejection faster. Regarding the cooperation between the United States and the European Union, you can seeUS and EU Intellectual Property Practice.

Inventor's signature and ownership, don't wait for authorization before arguing

US patent applications must specify the true inventor, and attribution errors can be addressed through a Certificate of Correction or Reissue, but the process is cumbersome and may be challenged. The common situation for Shenzhen teams is that the project is proposed by A, implemented by B, optimized by C, and only the name of the project manager is written in the disclosure document. This kind of ownership dispute encountered after authorization will directly affect the validity and qualification for patent protection.

We generally recommend conducting an inventor interview during the disclosure phase to identify each individual's contribution to specific claim features and confirm whether the service invention attribution agreement covers the US application. If cross-border e-commerce companies have multiple research and development teams, they should also pay attention to the different regulations on the ownership of job-related inventions in labor laws in different regions.

Treating disclosure as project management can save 6 to 9 months throughout the entire process

Returning to the question at the beginning. The official data shows that the average time from filing to the first examination opinion for a US invention patent application is around 15 to 20 months, but what really slows down the progress is the back and forth between the applicant and the agent. The disclosure document should be written clearly in one go, the attached drawings should be accurate in one go, the IDS should be collected in one go, and the R&D team should be able to cooperate in a timely manner when the OA responds. The actual goal of the entire process is to authorize within 24 months. On the contrary, it is not uncommon for the disclosure to be vague, the accompanying drawings to be repeated, and the response to be delayed for more than 3 years.
