As a patent agent or intellectual property consultant, I believe that when you contact the patent applicant, you must be asked by the customer: how long will it take for the patent to be authorized?You say: the invention is generally about 3 years, and the utility model is generally 7-14 months, and the time of specific cases will vary.The customer will be surprised! It's going to take so long? If the customer applied for a patent in the early years, it would be said that the utility model was not very fast, and could be authorized about half a year.You didn't see the official reply before. It was a little bit false after being questioned by the customer. Now the State Intellectual Property Office replies to the authorization time of three patent types.December 1, 2020，Consultant No. 310 of the State Intellectual Property Office answered the question on the authorization time of invention, utility model and design Under the condition of Patent Law：Invention patent applications can be authorized in about 3 years on averageThe average time of utility model patent application is about one yearThe average time of design patent application is about 0.5 yearsWhen the patent for utility model can be authorized about 1 year, and the relevant issues of patent authorization will continue to be found on the official website of the State Administration of knowledge. March 25, 2019，Consultant No. 210 of the State Intellectual Property Office replied: how long does it take from the date of application to the time limit for authorization?Limited by the number of applications, the writing standard of application materials and many other factors, utility model patent applications can be authorized in about 0.5 to 1 year under the conditions of patent law.From about the first half of 2019, the authorization time of utility model patents will be extended. At the same time, the State Intellectual Property Protection Bureau will also set up intellectual property protection centers in the Department cities. Patents in the relevant fields can go through the preliminary examination channel of the intellectual property protection center to speed up the authorization time.November 25, 2018，When consultant No. 210 of the State Intellectual Property Bureau answered the relevant questions, the application for utility model patent generally took about 0.5 to 1.5 years. At present, the way to speed up patent authorization is priority examination and rapid pre examination, but not all patents can be accelerated. Priority examination has requirements for the technical field. Rapid pre examination can only be carried out in the place where there is a local intellectual property protection center, and the patent field should be consistent with the pre examination field of the protection center There is also a squeeze on the cases, and the preliminary examiners are working overtime.Source: intellectual property rights in progress

A few days ago, Chuangyuan Institute received a final judgment of the Supreme People's court, which rejected the plaintiff's appeal and maintained the original decision that all patent rights were invalid. So far, Chuangyuan has been acting as an agent for Suzhou enterprises for 4 years and 2 months, and finally invalidated all the core invention patents of a famous multinational company.High efficiency heat exchange tube is the core component of central air conditioning equipment, which has been monopolized by German willand company for a long time. With a history of more than 180 years, veland company is the world's leading manufacturer of copper, semi-finished copper products and special copper alloy products. Its main products include copper strip, copper plate, copper tube, copper rod, copper wire, sliding bearing, finned tube, heat exchanger, etc. Willand group is headquartered in Ulm, Germany, and has a number of manufacturing enterprises, cutting centers and trading subsidiaries in many European countries, as well as in the United States, South Africa, Singapore and China.After long-term research and development, a Suzhou enterprise has finally made a breakthrough in the material and technology of high-efficiency heat exchange tube, entered the small batch trial stage, and obtained the recognition of international famous air conditioning manufacturers. At this time, the Suzhou enterprise received the lawyer's warning letter from veland company, believing that the Suzhou enterprise infringed the invention patent of veland company, and required the Suzhou enterprise to stop production immediately, otherwise it would bear all the consequences arising therefrom. Because the Suzhou enterprise invested a lot in R & D of this product and had a broad market prospect, it did not want to give up, so it entrusted Chuangyuan Institute to search and analyze the invention patents of veland company. As early as 2001, veland applied for a German patent for the high efficiency heat exchange tube and processing technology. In 2002, it entered China through the Paris Convention with international priority. In June 2006, it was granted a patent for invention. Based on this patent technology, veland has monopolized the domestic and foreign markets of the product for more than ten years, so it is very difficult to void the patent Big. After painstaking and detailed patent search and analysis, Chuangyuan Institute finally found the defects of the invention patent, and retrieved the reference documents affecting the inventiveness of the invention patent. Therefore, in July 2016, Chuangyuan Institute filed a patent invalidation request with the Patent Reexamination Board of the State Intellectual Property Office. After both sides' back and forth defense and oral trial, the Patent Reexamination Board of the State Intellectual Property Office made a patent invalidation decision in February 2017, declaring all the invention patents of veland company invalid, and Chuangyuan won the first battle as an agent for Suzhou enterprises.However, after receiving the patent invalidation decision, veland company thought that the determination of the reexamination board was wrong, so it filed an administrative lawsuit with Beijing Intellectual Property Court. Beijing Intellectual Property Court held a trial online in March 2020. In April, it made a judgment of first instance, rejected willand company's claim, maintained the decision that all patent rights were invalid, and Chuangyuan won another battle on behalf of Suzhou enterprises. However, after receiving the patent invalidation decision, veland company thought that the determination of the reexamination board was wrong, so it filed an administrative lawsuit with Beijing Intellectual Property Court. Beijing Intellectual Property Court held a trial online in March 2020. In April, it made a judgment of first instance, rejected willand company's claim, maintained the decision that all patent rights were invalid, and Chuangyuan won another battle on behalf of Suzhou enterprises. Since then, veland company still refused to accept and appealed to the Supreme People's court. After hearing, the intellectual property division of the Supreme People's court finally made a final decision in September 2020, rejecting veland company's appeal and maintaining the decision that all patents were invalid.So far, a patent invalidation dispute after 4 years and 2 months ended with the result that Chuangyuan won the lawsuit on behalf of Suzhou enterprises and the core invention patents of veland company were all invalid. It not only cleared the huge obstacles for the development of domestic high efficiency heat exchange tube industry, but also completely broke the long-term monopoly of international industry giants on the product. Invalidation of patent right refers to the system that any unit or individual who considers that the grant of the patent right is not in conformity with the provisions of the patent law can request the Patent Reexamination Board to declare the patent right invalid from the date when the State Intellectual Property Office announces the grant of the patent right. The establishment of the system of invalidation of patent right is to correct the wrong decision to grant the patent right to the invention creation that does not meet the requirements of the patent law, and to maintain the fairness of the grant of patent right.In practice, patent invalidation procedure is often used by the patentee's competitors to counteract patent infringement accusations. When a patent infringement lawsuit occurs, the defendant often turns to the State Intellectual Property Office to request the invalidation of the patent right, and the accusation of patent infringement is thoroughly dismissed. For the specific technology in the industry, the patent invalidation procedure will also be initiated if the industry thinks that the patent right has an improper monopoly.

When accepting the patent application entrustment, the patent agency usually requires the inventor to provide the technical disclosure. As the information carrier of patent technical solutions, technical disclosure can help patent agents quickly understand the technical background, technical solutions, technical effects and expansion space of patent applications, which is the basis of effective communication between patent agents and inventors. The complete, detailed and mature technical disclosure provided by the inventor is one of the important conditions for patent agents to write high-quality patent application documents. one、 General requirements for technical disclosureTaking an application for a patent for invention as an example, referring to the materials required to be submitted in the application specified in the guide to patent examination, the general patent agency suggests that the technical disclosure should include the name of the invention, the background technology, the purpose of the invention, the content of the invention, the beneficial effect of the application, the drawings and the attached drawings, the specific implementation mode, etc.Name of invention:The invention name shall describe the specific content of the invention accurately, comprehensively and briefly and embody the subject of protection is the product or / or method. The invention name shall use the technical vocabulary commonly used in the field, and avoid the use of the name of the person, unit, code, etc. The name of the invention shall be as specific as possible to avoid the use of words which are easy to produce ambiguity. The name of the invention shall be short, usually not more than 25 words, and in special cases, the name may be allowed to be increased to 40 words.Technical background:The development of the existing technology which is close to the application should be comprehensively described, and the problems and reasons in the existing technology should be objectively analyzed. Among them, the existing technical obstacles that can be overcome through the application shall be highlighted to reflect the key invention points of the application. The specific facts stated in this part shall indicate the origin, and the drawings may be attached if necessary.Purpose of invention:The technical problems that this application can solve should be emphasized directly and concisely.Invention content:The technical scheme applied for shall be clearly and completely described, and the technical principles of patents in different fields can be described from the perspectives of structure, process and formula. By reading the invention content, the technical personnel or patent agent in the field shall be able to understand how to realize the invention purpose of the application.Beneficial effects:The advantages of the application compared with the existing technology should be explained, and the improvement of the technical scheme compared with the existing technology should be pointed out. Generally, the beneficial effects can be explained from the aspects of productivity, quality, or accuracy improvement, energy conservation and environmental protection, and new functions.Attached drawings and descriptions:The parts in the attached drawings are numbered in Arabic numerals and the contents of the drawings are briefly described.Specific implementation mode:Several specific cases to achieve the purpose of invention shall be described in detail. According to the degree of beneficial effect, it can be divided into general implementation, preferred implementation mode and best implementation mode. The inventor can explain the embodiments by giving the specific experimental conditions and experimental results, introducing different parts connection and combination effect based on the application field. This part should not be understood as a simple repetition of the invention content, but should specify each technical feature of the invention content so as to fully support the feasibility of the invention.other:Other contents that the inventor considers helpful to the writing of the patent application document for invention can be provided. For example, the scope of protection (claims) the inventor expects, a list of prior patents related to the application, the possible alternative development of the technology, etc.two、 Writing skills1. Write a good technical background:When the inventor prepares the technical disclosure, he often thinks that the correlation between the background technology and the scope of patent protection is low, so he ignores the writing of the background technology and only subjectively describes his personal understanding of the current situation of the technology. However, complete background information can effectively avoid duplication of work, accelerate the patent application process and consolidate the scope of patent protection.Background technology refers to the existing technology that is useful for the understanding, retrieval or examination of inventions. When expounding the background technology, we should pay attention to the retrieval of journal papers and patent literature again, supplement the information source, avoid subjective conjecture; we should use scientific terms with practical significance, and avoid generalizing "Low efficiency", "waste of raw materials", etc.; the problems existing in the prior art shall be objectively described, and the technical obstacles that can be solved by the present application shall be mainly discussed, so as to avoid ambiguity or blindly belittling the prior art.2. Pay attention to the difference between the content of the invention and the specific implementation modeThe content of the invention is a general description of the technical scheme, and the specific implementation method is to illustrate the feasibility of the implementation of the invention with examples. The content of the invention is summarized from a plurality of specific embodiments, and the specific embodiments contain more details of operation or structure.For example, the content of the invention states that a certain kind of actual effect can be produced by a certain chemical reaction between 50 ℃ and 60 ℃. The specific implementation mode shall provide specific data of reaction under multiple specific temperatures (upper limit of recommended range, upper limit of preferred range, intermediate / optimal value, lower limit of preferred range and lower limit of range).It should be noted that when designing a subject with patent prospects, it is necessary to consider that the data under multiple experimental conditions may be submitted when applying for a patent, so as to reasonably design experiments and avoid repeated work.3. The expansion of the alternative is proposedThe development of alternative solutions provided by inventors can help patent agents expand their ideas and strive for a wider scope of patent protection. For example, on the basis of the existing content of the invention, the inventor may consider whether the object of the invention can still be achieved and produce beneficial effects after reducing, replacing or adjusting the parts, steps and processes. Even if this change will affect efficiency or reduce production, but to obtain a wider scope of protection will provide a good basis for future possible infringement litigation.This paper is based on the patent review guide and patent agency experience summary, for reference only.
