Patent Information

• Patent information refers to the technical and legal data contained in published patent documents. Each patent document contains a detailed description of the invention (how it works), claims (which define the legal scope), bibliographic information (inventors and filing date), and references to prior art. Globally, approximately 100 million patent documents exist. Because approximately two-thirds of the technical content in a patent is never published elsewhere, the patent corpus is the most complete collection of classified technological information.
  Patent documents are highly structured, with an abstract, detailed description, drawings, claims, and bibliographic information. This standardized format facilitates search and analysis. Patents are classified by technology field (using the International Patent Classification), which allows for more targeted searches. They frequently show practical applications of inventions. Because of this structure, patent databases enable detailed searches (by inventor, assignee, classification, keywords, and so on) across almost every field of technology.
  Patent databases are extremely useful to researchers, entrepreneurs, and inventors. They assist in surveying the state of the art in a field (to avoid duplication of effort), identifying emerging trends, and determining whether an invention is already patented. Reviewing patent literature can help innovators improve and identify potential licensing opportunities. Patent landscapes and analytics can help businesses plan their R&D strategies. Patents are also analyzed by the government and academics to determine the level of innovation.
  There are free public databases for patent searches. For example, WIPO's PATENTSCOPE offers searchable access to over 124 million international and national patent documents. National offices (e.g., USPTO, EPO) and private services (e.g., Google). Patent Lens also maintains extensive searchable collections. These tools enable users to retrieve the complete text, images, and legal status of patents.
  WIPO supports developing countries through programs such as ARDI and ASPI, which provide patent offices and institutions with advanced patent data and search tools. For example, under the ASPI program, eligible African universities and patent offices have free or low-cost access to sophisticated databases for retrieving and analyzing patent information. These initiatives enable local innovators to access global patent knowledge.
  Ethiopian innovators can align their research and development with global trends by leveraging patent information. EIPA actively promotes the use of patent information (one of its goals). The Authority assists with patent searches through its Innovation and Technology Transfer desk and the TISC network. Entrepreneurs and researchers should conduct patent searches early in the innovation process to make informed decisions about patenting or developing new products.
