Patent database search

When considering patent protection for your invention, a patent search is an excellent way to understand the possibilities. Not only will it give you insight into the likelihood of obtaining a patent, it can also help you develop a more effective IP strategy.

1. Four types of patent searches

• Patentability Search
  • When considering patenting an innovation, a patentability search is essential. Its main purpose is to determine whether the inventive step of the invention already exists. If similar technology is found, the invention may not meet the requirement of "novelty". In this case, there is little point in applying for a patent. However, if you find technology that is similar to your invention but not exactly the same, you can use it as a starting point to optimize your patent application.
  • Page Code Interpretation : Patentability search is the first step in patent application. Page Code recommends that you conduct a preliminary search through professional databases before submitting your application, and combine it with our professional analysis to ensure that your invention is patentable.
• Non-Infringement Search
  • The purpose of a non-infringement search is to determine whether an invention infringes an existing patent. It should be noted that patent applications are usually not made public until 18 months after they are filed, so there is a certain "blind spot". By searching expired patents or public documents, you can determine whether certain technologies can be freely used and implemented.
  • Page Code Interpretation : Non-infringement search is a key step to avoid legal risks. Our professional team can help you fully analyze existing patents to ensure that your innovation will not infringe on the rights of others.
• Invalidity Search
  • Invalidity searches are used to assess the validity and stability of a patent. If an existing patent related to an existing invention is found, an invalidity search can be used to determine whether the patent is actually valid. Some patents may have expired, have limited coverage, or may even be invalid due to improper authorization.
  • Page Code Interpretation : Invalidity search is a powerful tool for dealing with patent disputes. It can help patent owners analyze competitors' patents and find possible invalidity points, thereby creating more room for innovation.
• Patent layout analysis (Landscaping)
  • Patent landscape analysis aims to understand the patent landscape of a certain technical field, which can help right holders understand market participants, competitive landscape and emerging technological trends, so as to formulate more precise patent strategies.
  • Page Code Interpretation : Patent layout analysis is an important basis for enterprises to formulate long-term strategies. Through big data analysis and professional experience, it can help right holders gain insight into industry trends and seize technological commanding heights.

2. Steps for searching patent databases

• Select relevant patent documents: Search and screen 5-10 patent documents closest to the present invention in patent databases such as Espacenet.
• Discuss the prior art with patent attorneys: Based on the retrieved documents, identify the prior art and, based on this, highlight the unique features of the present invention.
• Determine next steps: Based on the search results, develop a plan of action for the next step, which may be to draft a new patent application or further analyze whether there is a risk of infringement.
• Page code interpretation : Patent search is a systematic process that requires the support of professional knowledge and experience.

3. Practical skills for searching patent databases

• Clarify the search goal: During the search process, avoid being distracted by a large amount of information and always focus on the core goal.
• Record search keywords: Record the keywords used to find relevant documents to facilitate subsequent optimization of searches.
• Gradually refine your search: Start with broad keywords and gradually add more specific criteria to narrow your search.
• Utilize classification codes: Combine classification codes and keywords to further improve the accuracy of search results.
• Quickly browse images: For mechanical engineering inventions, you can quickly filter related patents through images.
