Patents are the largest source of technological information. Patent are given to the inventor as a reward for its innovation in the form of the exclusive right of the monopoly for a period of 20 years from the priority date of the invention. Due to advancement in the IT sector and internet, now these valuable documents are in the reach of the general public. Any person skilled in the art can go through various patent databases and after a search can get the patent document of their need. There are different patent databases viz, USPTO, EPO, JPO, etc freely open for the public access. If we go through the patents related to a specific technological area, we will be able to find the lots of information about the life cycle of the technological innovation viz.,
o evolutionary path of a specific technology,
o technological development,
o technological diversification,
o technology merges,
o major players in specific technological area,
o key points of the specific technology,
“The World Intellectual Property Organisation (WIPO) revealed that 90% to 95% of all the world’s inventions can be found in patented documents.”
Patent analysis can reveals very valuable informations, which is not available anywhere. After patent search the crucial part is the patent analysis, and one have to be very concise about their objective of the study. The information in the patent documents can be utilized in different form according to the need and mapped accordingly to get the picture of the entire analysis in snapshots.
Patent data can be used for the preparation of technological landscapes. Logistic mathematics and circle mathematics can be very useful in the plotting of the technological landscape. It can reveal the evolutionary trend of a technology, how it is evolved from a basic technology, along with the period of the technological diversification and its nature. These maps will also give the detailed overview of the merging of the different technologies to give rise to break-through technologies. These types of maps will be very useful for the R&D personals to evaluate the position of their research and technology, and also they will find way to more innovate more advanced and valuable technology.
