  • If an inventor wants to protect his invention in a particular foreign country, he must apply for and be granted a patent by that country’s patent office because a patent issued by one country is not enforceable in another country. For example, a US patent is only enforceable in the United States. If the applicant also wishes to obtain patent protection for that invention in Japan, he will have to file for and be granted a patent by the Japanese Patent Office.
  • Most patent applications filed in US and international countries under the Patent Cooperation Treaty (PCT) are published 18 months after filing, and therefore very often represent the first published information available. Claims The claims are the part of the patent which define the scope of the legal protection sought for the invention. The description and drawings are used to interpret the claims.
  • PCT (WIPO): International Patent Application G-Pat: global patent – DE (Germany), GB (Great Britain), FR (France), CH (Switzerland) INPADOC: International Patent Document Center is an international patent collection. The database is produced and maintained by the European Patent Office (EPO). It contains patent families and legal status information, and is updated weekly. INPADOC was founded by the World Intellectual Property Organization (WIPO) and the government of Austria under an agreement on May 2 , 1972 . A little less than twenty years later, on January 1 , 1990 , it was integrated into the European Patent Office. An EPO sub-office was then created in Vienna , Austria. The INPADOC database, which is publicly accessible, provides information about patent families, i.e. corresponding patent applications, i.e., patent applications in different countries which claim the same priority and which normally disclose the same invention. It also provides information concerning the legal status of patent applications and patents in those countries which report status changes.

  • hong adj kong adj university adj of adj science adj technology Stopwords are terms that appear so frequently in document text that they lose their usefulness as search terms.
  • Keywords are more subjective as there are many words to describe the same concept. International Patent Classification (IPC) is used by all patent offices.

Let's assume that: You have invented a new tool and want to sell your idea. There are already patent applications for an identical tool. You are therefore not allowed to sell it in countries in which a protection right already exists. You can't apply for a patent either because the invention is no longer new. But you are allowed to put it on the market in other countries where patent rights are not granted. Hence, knowledge about the patent family will be useful - find out if further applications have been made in other countries.

  • EP1485389 Also published as: A single invention can be the subject of patent applications in many different countries. These related applications are listed under "also published as"…heading. These documents have exactly the same priority. Selecting any of them will give you access to a facsimile, allowing you to read the document in the language of your choice, the content is very similar, if not identical (other than in the language), to that of the document retrieved in the course of your search. Corresponding documents will only be listed if available in facsimile form. What is a cited document? A cited document is a document cited by the examiner in a search report. A cited document can be a patent document or an item of non-patent literature. In esp@cenet®, cited documents are available for European and PCT (WO) applications only. "View document in the European Register"? The European Register contains all the information pertaining to the patent application you are interested in, from first publication through to grant and beyond (legal status data, patent family details, etc.)

    • 2. Patents
      • What is a patent?
      • A patent for an invention is the grant of a protection right to the inventor to exclude others from making, using, offering for sale, or selling the invention for a set period of time (usually 16-20 years).
      • An inventor may sell or mortgaged or transfer the right to others.
      Therefore, inventor ≠ assignee/applicant
    • 3. Patents
      • What can be patented?
      • New & useful invention: design, industrial or technical process/method, machine, manufacture, or composition of matter, or significant improvement of the existing ones .
      • Why is patent a useful info. source?
      • Patent discloses sufficient technical details of an invention so the product/process can be reproduced.
      • Before applying for a patent, the inventor must do a "prior art search" (all patents in the classes / subclasses) to make sure that the claimed invention is indeed " new ".
    • 4. Patent Information
      • Databases for finding patents
