A technical assessment compares a utility model or design patent against prior art to determine if the granted right meets the basic requirements for stability and enforcement in court. This article 66 evaluation is a specialized procedure conducted by the National Intellectual Property Administration to verify the validity of patents that did not undergo substantive examination before being granted. Because utility models and designs are registered based only on a preliminary check, the law requires this secondary report before the owner can seek an injunction or damages against an alleged infringer.
The report provides a professional opinion on whether the patent is likely to survive an invalidation challenge by assessing its novelty and non-obviousness. It serves as a necessary piece of evidence in both judicial and administrative proceedings, providing the court or the enforcement bureau with a technical baseline. While the findings of the report are not legally binding on the judge, they carry heavy weight in the preliminary assessment of a case.
This mechanism prevents the abuse of unexamined patents to disrupt legitimate business activities and ensures that only robust rights are enforced.
Requesting a report from the patent office is the first step for any owner of a utility model or design patent who intends to initiate litigation. Under the framework of the article 66 evaluation, the patentee or an interested party must submit a formal application along with the required fee to the examination department. The examiner then conducts a comprehensive search of global patent databases and technical literature to find relevant prior art.
This search is much deeper than the initial check performed at the time of registration, focusing on the specific technical features of the claims. The results are compiled into a formal document that rates the patent’s validity on a scale, indicating whether the claims are likely to be upheld. If the report is negative, the patentee faces a high risk of having their patent invalidated if they proceed with a lawsuit.
This requirement forces patent owners to evaluate the strength of their rights before committing to expensive legal battles. It also provides a defense for the accused infringer, who can use a negative report to argue for the dismissal of the case. The administrative process usually takes several months to complete, which must be factored into the overall litigation strategy.
Courts in the People’s Republic of China look to the technical findings of the patent office to guide their decisions on preliminary injunctions and liability. When a plaintiff submits an article 66 evaluation report that supports the validity of their patent, the court is more likely to grant a stay of execution or a seizure of infringing goods. The report acts as an expert testimony from the state authority that issued the right, providing a level of technical credibility that the parties themselves cannot easily replicate.
However, if the defendant can produce new prior art that the examiner missed, the court may choose to ignore the report’s conclusions. This flexibility allows the judiciary to maintain its independence while still benefiting from the technical expertise of the patent office. In many cases, the court will suspend the infringement trial if an invalidation petition is filed based on the findings of the evaluation report.
This suspension prevents the risk of conflicting decisions where a court awards damages for a patent that is later declared void. The report thus functions as a stabilization mechanism for the entire intellectual property enforcement system.
Strategic use of technical assessments allows companies to manage their intellectual property portfolios and assess the risk of entering new markets. An article 66 evaluation can be requested even without an active dispute, allowing a business to check the strength of its own patents or those of its competitors. This proactive approach helps in identifying weak links in a portfolio that might be vulnerable to challenge.
For a foreign company operating in the manufacturing sector, obtaining a positive report for its core utility models provides a significant advantage in licensing negotiations or joint venture discussions. It demonstrates that the rights are enforceable and have been vetted by the national authorities. Conversely, discovering a negative evaluation early allows a company to adjust its product design or seek alternative licensing arrangements to avoid infringement.
The cost of obtaining the report is a minor investment compared to the potential loss from a failed litigation or an unexpected invalidation. This system encourages a more disciplined approach to patent filing where quality is prioritized over the sheer volume of registrations. The final report remains a permanent part of the patent record and can be accessed by other parties, promoting transparency in the patent landscape.
