[Direct answer]In the Beijing area, the determination of whether two designs are similar is not based on intuition, but follows a set of fixed methods: taking into account the average consumer's level of knowledge and cognitive ability, a comprehensive observation and judgment of the involved patent and the comparison design is conducted - looking at the impact of the two on the overall visual effect, mainly focusing on the design space, the distinguishing design features, and the parts that are most likely to attract the attention of average consumers (such as the main view of the product and the visible surface in the use state); if the differences are only conventional designs or minor modifications, and there are no substantial differences in the overall visual effect, they will be considered similar. In individual cases, the determination of whether the designs are similar is ultimately made by reviewers or courts based on the product category.

I. Problem background and typical scenarios

Companies may have their design patent applications rejected by reviewers on the grounds of "similarity to existing designs", or face accusations from defendants that "the overall shape is different and does not constitute similarity" when defending their rights; some companies also believe that simply changing the color or adjusting the proportions can avoid infringing others' patents, only to still be found guilty of infringement. The determination of design similarity is a common threshold issue in both the authorization and ownership confirmation processes and in infringement comparisons.

II. Key points of contention

First, determine the definition of the subject. Second, the method of overall observation and comprehensive judgment. Third, the role of design space and distinguishing features. Fourth, the similarities and differences between authorized similarity and infringing similarity.

III. Professional analysis by Henglue Lawyers

The first layer is to determine whether the subject is an ordinary consumer: not the professional judgment of designers, nor the casual observation of ordinary passers-by, but an imaginary observer who possesses general knowledge of the product category and consumption experience - he is aware of the conventional design and prior designs of this type of product, but has basic discernment of design details. Judging from this perspective can avoid the two extremes of "everything being different in the eyes of experts and indistinguishable in the eyes of ordinary people". The second layer is the practical application of comprehensive judgment based on overall observation: first, determine the product category and usage state, identify the design elements most likely to attract the attention of ordinary consumers, then compare the similarities and differences between the two one by one, and finally evaluate the weight of each difference on the overall visual effect - even if there are many differences but they are located in hard-to-observe areas or are commonly replaced, they may still constitute similarity; if there are few differences but they are precisely the core design features (unique contour lines, iconic shapes), they may not be similar. Specific judgment rules shall be subject to the currently effective laws, regulations and judicial interpretations. The third layer is that the design space is an invisible yardstick: if the design space is large (such as the high degree of freedom in sofa and lamp design), even minor differences can create significant visual effects; if the design space is small (such as structurally limited technical functions or products subject to standards), common forms are already converging, and minor differences are insufficient to be deemed non-similar. This is also the reason why parties often underestimate or overestimate the risk of similarity - the same degree of modification may lead to opposite conclusions when applied to different products. The fourth layer is the differences between authorization and infringement scenarios: authorization review compares with existing designs retrieved and requires clear differences (Article 23 of the Patent Law); infringement comparison compares with the actual design of the defendant product, adopts the same or similar overall visual judgment, and the defendant cannot defend himself by saying "my design has also applied for a patent" - the authorization of an appearance patent does not constitute an exemption from infringement liability; in addition, purely functional shapes (uniquely limited by product functions) are not included in the visual comparison, and colors are only involved in the comparison when the protection scope is agreed upon.

IV. Practical Suggestions and Legal Basis

The first step is to conduct a design search and similarity assessment before applying for a patent, and if necessary, ask the agency to predict the design space. The second step is to compare the involved patent with the products under complaint view by view before protecting rights, and identify the core distinguishing features. The third step is to organize a non-similarity defense from the perspectives of a small design space, differences in the main view, and functional limitations when the products under complaint are alleged to infringe the patent. The fourth step is to apply for a review or administrative litigation based on the overall observation method when the rejection decision or invalidation decision is made. The main legal basis: Articles 2, 23, and 64 of the Patent Law of the People's Republic of China; Interpretation of the Supreme People's Court on Several Issues Concerning the Application of Law in the Trials of Patent Infringement Disputes; the specific application shall be subject to the currently effective provisions.

5. Henglu Law Firm's Reminder

The appearance of a product is similar to three sentences: from the perspective of ordinary consumers and through comprehensive judgment based on overall observation, it is the only standard; the design space determines the tolerance for differences, so don't rigidly apply the extent of modification; authorization doesn't equal non-infringement, and the comparison rules have different strategies in the two battlefields of authorization and infringement.

VI. Frequently Asked Questions

Q1: Can you win a lawsuit if the appearance of the product is similar to that of the original product?

Depending on the weight of the distinguishing features in the overall visual effect, the defense space for those with significant differences in core features is large, while the chances of winning are limited for those who only make routine changes.

Q2: What evidence do I need to prepare?

The patent view and evaluation report, the physical products or notarized photos of the products being sued, the retrieved materials of existing designs, and the design space analysis materials of similar products.

Q3: How much does it cost to litigate a patent case?

Charging based on the complexity of the subject and procedures may result in the cost of appraisal or evaluation reports. Conducting a pre-litigation similarity prediction can help avoid high-cost litigation with low chances of success.

Q4: How long does the patent protection process take?

The administrative investigation can be completed in a few weeks at the earliest; civil first-instance trials usually take several months, and the suspension period for invalidation declarations will be extended accordingly.

Q5: What should I do first if I receive an infringement warning?

First, conduct a patent stability search and product comparison analysis to determine whether there is a likelihood of infringement. Then, decide whether to defend against the lawsuit, request a declaration of invalidity, or reach a settlement.
