That data is: the total number of unique patents in the forward citation tree. More valuable patents (that is, patents for which there is relatively high demand for the technology described in that patent) tend to be cited more often than less valuable patents. One of the main limitations is the lack of scholarly attention paid to the dynamic influences arising from the evolution of technology fields. Patent examiners decide which citations to include in the final patent document, even adding citations to prior art of which the applicant may have been unaware.1 The citations that a patent receives from subsequent patents are called forward citations. Downloadable (with restrictions)! Search and read the full text of patents from around the world with Google Patents, and find prior art in our index of non-patent literature.

The successfully sold 167 singleton patents form the sample of our study. The number of forward citations received by a patent (or patent application) is particularly linked to the technological rather than economic importance of the innovation. Next, one may compare the number of times each patent is cited by later patents—or “forward citations”—with the median number of forward citations received by its comparable group of patents. Forward Citations as a Patent Relevance Metric. From here, you can go further and get References Cited by any one of the displayed results by selecting Backward Citations from the Advanced Features. While preparing a recent analysis of leading Microsoft (and Google and Apple) patents we came across US patent 8077153, for Precise selection techniques for multi-touch screens.This was one of the highest ranked Microsoft patents in our analysis (suggesting a high forward citation count), but very surprisingly Google Patent only showed a forward citation count of 4. Alternatively, the specific patent can be cited as prior art by another patent – this is a “forward citation.” Patent citations exist because a patent examiner searches the patent prior art to identify any prior disclosures of the same or similar technology. Cited-Forward and Cited-Backward Citations on TotalPatent One Plaintiff argued that the district court should follow Oracle, where the Northern District of California held “that failing to include citation counts to patents (in that case, predecessors to a reissue patent) that have ‘the same specification and drawings’ was a fatal flaw in [an] expert’s forward citation count.” (Dkt. The “Color by” menu makes it possible to distinguish the analyzed Fampat patent … The intuition is simple: elds with greater innovative activity will have more value to protect and will do so by applying for more patents.

Analysis of patent citations can be used to get an idea of the technology growth and also to measure the quality of patents. To all - I have from time to time noticed the USPTO may list Patent A (being a US patent) as a backward citation to Patent B (also a US patent), but not Patent B as a forward citation to Patent A. Overview: Access to prior art citations Citations/references are usually presented as Bare listings of citations, for example lists of publication numbers only Citations in search reports supplemented with further useful information Forward citations of patents have been used extensively to capture the impact of technological knowledge. Since one patent may appear in several different branches of a forward citation tree, it may be useful to know how many unique patents are actually in the tree; The dark green line shows the forward citation count by years from publication date for the broader set of issued US patents (set i). SUMMARY OF THE INVENTION Technical Problem. Patents renewed to full-term were significantly more highly cited than patents allowed to expire before their full term. For years, researchers have used patent citations as a way to measure various aspects of the innovative ecosystem. As a proxy of patent value, forward citation counting is widely used, but it takes a long time for a patent to be sufficiently cited. These data comprise detail information on almost 3 million U.S. patents granted between January 1963 and December 1999, all citations made to these patents between 1975 and 1999 (over 16 million), and a reasonably broad match of patents to Compustat (the data … The successfully sold 167 singleton patents form the sample of our study. Forward citations of patents have been used extensively to capture the impact of technological knowledge. Seminal work by Griliches measured patent counts (Griliches 1981), and later work weighted such counts by the number of forward citations received by each patent on the view that more important patents receive more references (Trajtenberg 1990). A useful, efficient and increasingly utilised indication of the value of a patent is the number of times that it is cited by a later patent (‘forward citations’). This article aims to compare the existing approaches, such as citation-lag distribution, Tobit regression, and multilayered neural network to forecast forward patent citations as a proxy for patent technological impact. Compared to other value indicators in patent data, forward citations are perhaps the most studied and the most "accepted" measure of a patent's value or significance. Here, we discuss why forward citations can be relevant when performing some form of patent valuation. Reviewing Comcast’s argument that a "forward citation analysis" was an unreliable method to estimate the value of an asserted patent, the court found that the case Comcast cited did not actually discredit the method, and that other cases, publications, and studies had … METHOD 2 : ENTER A NEW PATENT TO FIND REFERENCES CITING ANY PATENT.

Thus, an earlier-published patent cited by a total of 10 patents would have 10 forward citations (FC). There are basically two kinds of citations viz; backward citation and forward citation. Forward citation tracing: Refers to the process of finding the newest articles, books or book chapters that cite a particular paper, book, or book chapter. Patents are cited for two principle reasons. First, backward citations provide examples of the existing related art. In the case of applicant-provided IDS citations, the citations let the examiner know that the art was considered and the claims were carefully crafted around the prior art. Forward citations accrue over time as patent examiners and applicants refer to prior pat- ents during the prosecution of new applications (Hall et al. A search of subsequent U.S. and German patents yielded counts of citations to those patents. Consequently, as the court pointed out, the "patent with the highest number of forward citations is (unsurprisingly) the oldest patent in this suit. Some claim that the number of forward citations for a specific patent can indicate a patent's relevance and that more highly cited patents are … For a given patent (or patent application), a forward citation is another patent document’s citation back to that given earlier patent (from the perspective of the given patent). Overview: Access to prior art citations Citations/references are usually presented as Bare listings of citations, for example lists of publication numbers only Citations in search reports supplemented with further useful information Our study entails: selecting groups of patents issued at least 20 years, and some as far as 30 years ago; extracting the number of forward citations issued each year for each patent through 2008; and fitting the cumulative forward citations to a variety of models such S-, linear, quadratic and logistic curves. A document searching system searches for other documents having a user-specified document cited therein as its referred document to thereby uncover the latest document associated with the user-specified document. The package is made up of a single python class, scraper_class. The higher an invention's economic value estimate was, the more the patent was subsequently cited. Forward citations of patents have been used extensively to capture the impact of technological knowledge. Patent count & forward citations for entire CPC category. The Chinese ‘754 patent has international patent family members associated with it (EP894799A1 and WO1998031684A1 for instance) which do have forward citations associated with them.

CITATION LIST Patent Document. It also facilitates the commercialization and transactions of patents. I would like to have some very rough idea of the state of innovation in specific technological fields. In contrast, when a target patent is cited by later patents (i.e., forward on the time axis), such citations are called “forward citations.” Since this perspective is relative, any patent–patent citation is “a backward citation” for the citing patent and, simultaneously, “a forward citation” for the cited patent. We focus on evaluating the validity of the patent citation count theory. Patents without established market values (e. g., no negotiated royalty rates) are often valued by comparing the number of citations the patent has received to the numbers received by other patents whose market values are established. Forward references are patents or applications that cite or reference the document in question. [ Top ] Relationship Between the Two Tables There is a circular relationship between the Backward andForward citations.
