@article{bessen2007empirical,
title={An Empirical Look At Software Patents},
author={Bessen, James and Hunt, Robert M.},
journal={Economics & Management Strategy},
year={2007},
abstract={U.S. legal changes have made it easier to obtain patents on inventions that use software. Software patents have grown rapidly and now comprise 15 percent of all patents. They are acquired primarily by large manufacturing firms in industries known for strategic patenting; only 5 percent belong to software publishers. The very large increase in software patent propensity over time is not adequately explained by changes in R&D investments, employment of computer programmers, or productivity growth. The residual increase in patent propensity is consistent with a sizeable rise in the cost effectiveness of software patents during the 1990s. We find evidence that software patents substitute for R&D at the firm level; they are associated with lower R&D intensity. This result occurs primarily in industries known for strategic patenting and is difficult to reconcile with the traditional incentive theory of patents.},

abstract={In this paper we examine the panel data estimation of dynamic models for count data that include correlated fixed effects and predetermined variables. Use of a linear feedback model is proposed. The standard Poisson conditional maximum likelihood estimator for non-dynamic models, which is shown to be the same as the Poisson maximum likelihood estimator in a model with individual specific constants, is consistent when regressors are predetermined. A quasi-differenced GMM estimator is consistent for the parameters in the dynamic model, but when series are highly persistent, there is a problem of weak instrument bias. As estimator is proposed that utilizes pre-sample information of the dependent count variable, which is shown in Monte Carlo simulations to possess desirable small sample properties. The model and estimators are applied to data on US patents and R&D expenditures.},

@article{hall2005exploring,
title={Exploring the patent explosion},
author={Hall, Bronwyn},
journal={Essays in Honor of Edwin Mansfield},
pages={195--208},
year={2005},
abstract={This paper looks more closely at the sources of patent growth in the United States since 1984. It confirms that the increase is largely due to US patenters, with an earlier surge in Asia, and some increase in Europe. Growth has taken place in all technologies, but not in all industries, being concentrated in the electrical, electronics, computing, and scientific instruments industries. It then examines whether these patents are valued by the market. We know from survey evidence that patents in these industries are not usually considered important for appropriability, but are sometimes considered necessary to secure financing for entering the industry. I compare the market value of patents held by entrant firms to those held by incumbents (controlling for R&D). Using data on publicly traded firms 1980-1989, I find that in industries based on electrical and mechanical technologies the market value of entrants’ patents is positive in the post-1984 period (after the patenting surge), but not before, when patents were relatively unimportant in these industries. Also, the value of patent rights in complex product industries (where each product relies on many patents held by a number of other firms) is much higher for entrants than incumbents in the post-1984 period. For discrete product industries (where each product relies on only a few patents, and where the importance of patents for appropriability has traditionally been higher), there is no difference between incumbents and entrants.},

author={Hall, Bronwyn H and Jaffe, Adam B and Trajtenberg, Manuel},
year={2001},
institution={National Bureau of Economic Research}
abstract={This paper describes the database on U.S. patents that we have developed over the past decade, with the goal of making it widely accessible for research. We present main trends in U. S. patenting over the last 30 years, including a variety of original measures constructed with citation data, such as backward and forward citation lags, indices of originality and generality, self-citations, etc. Many of these measures exhibit interesting differences across the six main technological categories that we have developed (comprising Computers and Communications, Drugs and Medical, Electrical and Electronics, Chemical, Mechanical and Others), differences that call for further research. To stimulate such research, the entire database about 3 million patents and 16 million citations is now available on the NBER website. We discuss key issues that arise in the use of patent citations data, and suggest ways of addressing them. In particular, significant changes over time in the rate of patenting and in the number of citations made, as well as the inevitable truncation of the data, make it very hard to use the raw number of citations received by different patents directly in a meaningful way. To remedy this problem we suggest two alternative approaches: the fixed-effects approach involves scaling citations by the average citation count for a group of patents to which the patent of interest belongs; the quasi-structural approach attempts to distinguish the multiple effects on citation rates via econometric estimation.},

The empirical analysis uses detailed data compiled for a sample of 252 patent suits and reveals patterns generally consistent with those suggested by the model.},

abstract={The cost of engaging in litigation over intellectual property assets diminishes their value as an incentive to invest in research. The frequency of court cases ref ectsfirms' strategies for appropriating innovation rents. We examine the characteristics of litigated patents and their owners by combining, for the first time, information about patent case filings from the U.S. district courts with detailed data from the U.S. Patent and Trademark Office. By comparing filed cases to a control group, we show that there is substantial variation across patents in their exposure to litigation risk. We use this empirical evidence to examine hypotheses about the determinants of patent suits.},

This pattern is consistent with the literature of costly litigation, which suggests that firms that have high litigation costs will take greater precautions to avoid litigation. These results are robust to a variety of control variables and modifications that seek to test alternative explanations.},

It introduces into the subject-matter by discussing an empirical problem, the relationship of nano-publications and nano-patents as representations of nano-science and nano-technology. Drawing on a variety of sources, different interpretations of patent citations are presented. Then, the nature of patent citations is further investigated by comparing them to citations in the scientific literature. After characterizing the citation linkage as indicators of reciprocal relationships between science and technology, patent citations in nano-science and technology are analyzed in terms of interfield and organizational knowledge-flows.},

For all these games, the sets of pure strategy Nash equilibria, correlated equilibria, and rationalizable strategies have identical bounds. Also, for a class of models of dynamic adaptive choice behavior that encompasses both best-response dynamics and Bayesian learning, the players' choices lie eventually within the same bounds. These bounds are shown to vary monotonically with certain exogenous parameters.},
