A patent may both be reclassified to the industry where the invention took place, or to the user B.L. Basberg / Patents and the measurement of technological change industry. The patent owner will most likely repre- sent the industry of origin, and the researcher needs a detailed knowledge of different industries to be able to find the Cited by: It concludes that patent data represent a valuable resource for the analysis of technological change.

They can be used to study longer-run interfirm differences in inventive activity and as a substitute for R&D data where they are not available in the desired detail. Moreover, patent renewal data, which are also becoming available in the U.S., allow one to construct more relevant "quality weighted" inventive "output" measures.

Patent data are considered to be result-based indicators of innovation and the reflection of technological and scientific changes and inventive processes [7]; and are capable of "appropriately Author: Daniele Archibugi.

The Value of Patents as Indicators of Inventive Activity Zvi Griliches, Ariel Pakes, and Bronwyn II. Hall* 1.

We first develop an index of patent ‘quality’ using detailed information on patents in the U.S. in seven technology fields. Using a factor model, we construct a minimum-variance index based on four patent characteristics.

This data set and information about patent institutions allow inferences about changes in the quality of patent examination. Allison and Lemley () and Jaffe () discuss trends in increasing patenting activity over the past two decades, and Merges () discusses the possible ramifications on patent litigation and incentives to innovate.

At the same time we find no evidence of technological exhaustion at the micro level, i.e., there are no negative time trends in research productivity, conditional on the level of R&D. We find that differences in (average) patent quality across firms are strongly.

The innovation literature has argued that forward patent citations are a good indicator of the quality of the innovation. Hall, Jaffe, and Trajtenberg () and Nicholas () have argued that forward citations are also correlated with the private value of patents based on a regression of a firm's Tobin's Q on its stock of citation-weighted Cited by: MEASURING THE TECHNOLOGICAL AND ECONOMIC VALUE OF PATENTS Several experimental composite indices, based on groups of relevant factors, generated consistent results.

How To Measure Patent Quality: A View from Silicon Valley We’re continuing our patent quality discussion by tackling the issue of measurement.

How to measure patent quality is an appealing topic for everyone who especially subscribes to a “you. ‘Quality’ Of A Patent: Test Of Inventive Step; Patents are mostly sought for inventions which vary from the known only with respect to some minor element or detail.

An alleged invention may be said to consist purely in putting two known things together to make a single thing. To put Patent Valuation methods into context, simple patent counts are already being integrated into European policy.

For example the European Trend Chart- a monitor of inventive activity in Europe uses two patent based indicators. The use of patent valuation methodologies is also becoming commercialised.

Patent statistics: A good indicator for innovation in China. Patent subsidy its disadvantages in terms of timeliness and thus cannot reflect recent changes in patent quality. Moreover, the two lines of research seem to be parallel when dealing with patent quality.

Studies based on survey data have illustrated exaggerated. For each patent accepted by the U.S. Patent Office, a patent reviewer will file the patent under several classes within both classification systems.

For instance, a solar photovoltaics patent may be entered under the U.S. classes “batteries” and “active solid-state devices” and within the international system as “semiconductor devices.”.

By considering a regional sample of Italian inventors, this paper explores the factors behind the different individual performances in terms of number and quality of patents. Our reference population is composed of inventors residing in the Marche region who, over the periodhave contributed to patent applications filed at the European Patent Office.

Lemley, Robert P. Merges. Measuring Outputs and Outcomes of Innovation As described in Chapter 4, innovation output may be indicated by statistics on patents, papers, prizes, invention disclosures, and degrees awarded, while outcome proxies include patent and paper citations, expert evaluations, innovation counts, new product sales, measured productivity growth, and.

For those with a deep interest in patent evaluation and value assessment, True Patent Value is a thoughtful and thought-provoking resource.

After outlining core concepts in patents and their valuation, the book dedicates pages to case studies and anecdotes associated with more than two dozen patents from court cases, ITC actions, patent pools, patent sales and PTO /5(6). A patent is a single document with coverage over a specific region (US, EPO designated countries, etc.) A patent family is a collection of docs from different patent offices with coverage of the same invention BUT.

The precise definition and scope of a patent may vary in different regions, so that there can be 2 equivalents in oneFile Size: KB. The central idea of this paper is that innovation systems are a very important determinant of technological change.

We describe that the emergence of a new innovation system and changes in existing innovation systems co-evolve with the process of technological by: and identify a specific technological trend. Second, in prior research, patent citation lags used to distinguish between innovations of different quality have been too short to distinguish between incremental and radical innovations.

Lags of ten years and longer are recommended. Short lags may obscure patent-based comparisons of firm. The Design Publication Quality program was created as a patent quality advancement to improve the image quality of published design patents.

RESEARCH, PATENTING, AND TECHNOLOGICAL CHANGE1. This paper develops a search-theoretic model of technological change that accounts for some puzzling trends in industrial research, patenting, and productivity growth.

In the model, researchers sample from probability distributions of potential new production techniques. The paper contains the fundamental findings and equations relating technological improvement to a variety of patent characteristics. Technological dynamism InMagee began determining the.

Hence, to avoid infringement of a patent, changes to a product or process must be made to avoid literal infringement and infringement under the Doctrine of Equivalents.

Myth: The percentage difference of a product compared to a patented product does not indicate whether the product infringes on claims of the patent. The second uses patent data as an indicator of inventive activity, relying on the fact that patent offices attempt to apply fairly uniform standards of novelty and inventive step when granting patents, so that counts based on them should reflect the innovative activity in a society or in a particular industrial or technology Size: 67KB.

The inventive step and novelty tests should better target an innovation’s technical features. This would help ensure the patent system targets technological innovations, especially where innovations are based on a mix of technical and non-technical features, or mainly involve obvious and/or trivial combinations of pre-existing objects.

The recently released USPTO Office Action dataset (Lu, Myers and Beliveau ) allows for further assessment of the informational content of patent citations. The figure above displays the textual similarity between the claims from a focal patent and the claims contained in the focal patent’s citations (what we call invention similarity).
