AIDB, the Italian Patent Information Users Group

The Italian Patent Information Users Group (AIDB—Associazione Italiana Documentalisti Brevettuali) was founded on February 24, 2004. At the end of that year, AIDB had 58 members, coming from different environments such as industry, private practice, public institutions, and content providers. During its first months of existence, AIDB coordinated various activities such as checking the extent and quality of documentation services offered by the Italian Patent and Trade Mark Office (UIBM), and promoting discussions about suitable certification schemes for professional patent searchers. In November 2004, AIDB organized a two-day national patent information conference, focused on the business impact of patent information and on the certification of patent searchers.

Patent predictive price-to-book ratio (PB) on improving investment performance -- Evidence in China

Patent is strongly meaningful for most countries’ technology development and economy growth. China is the world largest patent application country and has the world No.2 stock market. In this research, China listed companies (A-shares) in Shanghai main board, Shenzhen main board, GE board, and SME board from 2016 to 2018 were applied to discuss the prediction ability of patent indicators to financial performance. The patent prediction equations for quantitatively predicting the price-to-book ratio (PB) by patent indicators were constructed via Granger Causality test and time series regression. The stock selection criteria based on the patent predictive PB were further discussed. The traditional value investors consider stocks with PB values under 3.0 are undervalued. It was found that most stock portfolios selected by either the lower predictive PB or the higher predictive PB growth rate had higher performance above the traditional PB investment strategy. The criteria also worked well on GE board and SME board even though these stock boards were seriously impacted to decline by the China-US trade conflict. Though the overall economic environment fluctuated, the patent prediction algorithm proposed was proved to be useful to discover good stock portfolios and improve traditional PB investment strategy

Patent analyses in the changed legal regime of the US Patent Law since 2001

In 2001, a new ruling for the publication of patent applications at the United States Patent and Trademark Office came into effect. Since then, all applications which are also filed with foreign offices have to be published 18 months after the application date, in analogy to the ruling in Europe and Japan. This new regime replaces the former system where only granted patents were published. With about 70% of all applications the share of pre-grant publications of applications of US origin is quite high, allowing new types of statistical analysis. In particular, the investigations of time series based on priority years instead of grant years can thus be performed much more topically. On the one hand, a larger dataset for applications of US origin is available; on the other hand, the sample of applications from Asian countries is generally much larger at the US Patent Office than at the European Patent Office. Despite these new opportunities, searches at low levels of aggregation by codes of the International Patent Classification still have to be handled with care.     

The classification of plants in the United States Patent Classification system

More than 11 100 plant patents have been granted US Patent and Trademark Office since 1931. The system for classifying such patents for efficient retrieval is a specialized part of the United States Patent Classification. It is described here under the following topics: purpose, the classification schedule, schedule organisation, relationship to design and utility patent classification, class definition, search notes, line notes, hierarchy, and special features of plant patents, such as coloration and the effect of commercial or market practice. The article then considers placement rules for consistent classification of such patents, searching for a patented plant, and aids for such searching. Illustrative examples of the schedule, and of the placement of and retrieval of plant patents are provided.     

Analysis of the patent cooperation network in global artificial intelligence technologies based on the assignees

Studying the distribution of the patent cooperation networks from the perspective of assignees provides a very important reference to improve the analysis of the market situation, master the layout of industrial technology and seek partners or mergers and acquisitions. This study uses the Derwent patent database and the patent metric approach to investigate the cooperative network structure of the assignees. The overall patent output in the artificial intelligence field on a global scale exhibited a rapid growth, and the proportion of cooperative patents significantly increased; the cooperation structure between the assignees was loose, and the innovation efficiency was low.
