Patent are the most useful form of data on the market for competivie analysis. Unique indicator are getting applied to predict the value of a patent or any company's strength. Tech-Line® uses three regular patent indicators and six advanced citation indicators invented by CHI to analyze corporate technological strength.
All indicators are calculated for certain businesses, in certain technologies over a time period. Since patent citation rates differ by technology, comparisons need to be made only inside comparable technologies groups.
Basic Indicators
* Number of patents
* Patent growth percent in area
* Percent of business patents in area
Patent Citation Indicators
* Cites per patent
* Present impact index (CII)
* Technologies strength (TS)
* Technologies cycle time (TCT)
Science Linkage Indicators
* Science Linkage (SL)
* Science Strength (SS)
Simple Indicators
Tech-Line uses 3 indicators based on patent counts:
Number of Patents - A count of a company's patents issued in the U.S. patent program. Simply because the U.S. is such a big market place, even non-US firms seek the protection of a U.S. patent for their most very important innovations. By tracking number of patents, growth in patenting and distribution across technologies locations, you can monitor and compare the evolution of companies' R&D activity by technology region. Number of patents tracks R&D spending but can be disaggregated across technologies whereas R&D spending often can't.
Patent Growth Percent in Location - The change in the number of patents from one time period to another, expressed as a percentage. This identifies technologies receiving escalating emphasis and those in which innovation is slackening off. It also identifies firms escalating their technological development, and those whose R&D is played out.
Percent of Organization Patents in Area - The number of patents in a technologies region divided by the total number of patents for that provider, expressed as a percentage. This tells you which technologies form the core of a company's intellectual property portfolio.
Patent Citation Indicators
Four Tech-Line indicators are derived by analyzing the references on the front pages of patents, or "patent citations." References are placed on patents to aid establish the novelty of the invention. Inventions must be novel to be awarded a patent. To enable the patent office examiner to assess the novelty of the invention, a patent document lists "prior art" in the form of references to prior patents in the same area. Patent citations also play an crucial role in patent infringement litigation by delineating the domain of the patent.
In counting citations, we reverse the perspective and count how numerous citations a patent receives from subsequent patents. This is a way of counting how a lot of times a patent becomes prior art in future technological advances. Analysis has established that highly cited patents represent economically and technically important inventions. Particulars on the history and validity of patent citation analysis are in the Tech-Line background paper.
Cites Per Patent- A count of the citations received by a company's patents from subsequent patents. This allows you to assess the technological impact of patents. High citation counts are normally related with fundamental inventions, ones that are basic to future inventions. Firms with highly cited patents may be extra advanced than their competitors, and have alot more beneficial patent portfolios.
Existing Impact Index (CII) - The number of occasions a company's prior five years of patents are cited in the current year, relative to all patents in the U.S. patent program. Indicates patent portfolio high quality. A value of 1. represents average citation frequency a value of 2. represents twice typical citation frequency and .25 represents 25% of typical citation frequency. In a Tech-Line corporation report, you can identify the technologies in which firms generate their best function. In a Tech-Line technologies report you can benchmark a company's technological excellent against other organisations and against the typical for the technology. (CII's vary by technology. For example, they are high in semiconductors, biotechnology, and pharmaceuticals, and low in glass, clay & cement, and textiles.) CII has been found to be predictive of a company's stock market place performance.
Technology Strength (TS) - Quality-weighted portfolio size, defined as the number of patents multiplied by current impact index. Working with Technology Strength you may uncover that while 1 firm has much more patents, a second might possibly be technologically significantly more effective for the reason that its patents are of superior high quality.
Technology Cycle Time (TCT) - Indicates speed of innovation or how rapid the technology is turning more than, defined as the median age in years of the U.S. patent references cited on the front page of the company's patents. Organizations with shorter cycle occasions than their competitors are advancing far more promptly from prior technologies to existing technologies. In semiconductors, cycle occasions are short (three-4 years) in shipbuilding they are lengthy (extra than 10 years). The typical is 8 years. In fast moving technologies, TCT allows you to identify organizations that may well gain the benefit by innovating additional easily.
Science Linkage Indicators
Two Tech-Line indicators are derived by analyzing the front page of patents. Patent documents need to cite relevant prior art (see patent citation). Increasingly, patents are citing non-patent documents as prior art, and many of these are papers in scientific journals. Tech-Line's Science Linkage and Science Strength indicators are based on counts of patent references to scientific papers. Patents that reference numerous scientific journal articles are numerous from patents that reference none. For example, a patent on a genetically engineered seed, or on a neural network based method manage might possibly reference 10 or a great deal more scientific articles. In contrast, an improved style for a part of a motor may perhaps reference none. Tech-Line's indicators develop on this distinction, differentiating companies and technologies that are high-tech from those that are not. This is particularly useful in locations like agriculture, where patents for plows are mixed in with advanced agrobiotechnology. Science Linkage can differentiate between the two.
Science Linkage (SL) - The typical number of science references cited on the front page of the company's patents. High science linkage indicates that a company is building its technologies based on advances in science. High-tech providers tend to have greater science linkage than their competitors. Science Linkage enables you to pick out the high-tech players in even classic areas such as agriculture or textiles. Science Linkage has been discovered to be predictive of a company's stock market place efficiency.
Science Strength (SS) - The number of patents multiplied by science linkage. Indicates the total quantity of a company's science linkage activity. Science strength reminds us that despite the fact that a modest biotech firm may use science highly intensively, a large pharmaceutical firm in reality has a greater reliance on science simply because it makes use of investigation across a a lot larger R&D effort
