However, we still lack consistent results whether the diversification has positive effects. We focus on the relevance of its measures as one of the causes of the inconsistency. This study aims to develop a technological diversification measure by including relativity of firms' technological portfolio, because major conventional methods, e.g., Herfindahl–Hirschmann Index and entropy, consider only one firm's absolute portfolio. We analyzed each firm's relative position from a common core of the industrial technologies for four global major firms in Fast Moving Consumer Goods sector. The product set of International Patent Classification (IPC) among them was defined as the core of industrial technology. We quantified firms' chronical shifts from there, and compared them with those by conventional methods. The proposed measure clarified the firms' relative positions in a manner that conventional ones cannot identify. The firms' qualitative information supported the validity of the observations. Our approach can take more IPC data into account, less affected by the largest number of IPC, which are among its advantages; it further allows for analysis from new aspects that complement the conventional “absolute technological portfolio” measures.</div></div>","PeriodicalId":51794,"journal":{"name":"World Patent Information","volume":"80 ","pages":"Article 102333"},"PeriodicalIF":2.2,"publicationDate":"2024-12-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143180293","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Self-information is calculated based on a probability of occurrence of the claim, where this probability is obtained from a language model. Grounded in information theory, this approach is based on the assumption that an unlikely concept is more informative than a usual concept, insofar as it is more surprising. In turn, the more surprising the information required to define the claim, the narrower its scope. Seven language models are considered, ranging from simplest models (each word or character has an identical probability) to intermediate models (based on average word or character frequencies), to large language models (LLMs) such as GPT2 and davinci-002. Remarkably, when using the simplest language models to compute the probabilities, the scope becomes proportional to the reciprocal of the number of words or characters involved in the claim, a metric already used in previous works. Application is made to multiple series of patent claims directed to distinct inventions, where each series consists of a set of claims having a gradually decreasing scope. The performance of the language models is then assessed through several ad hoc tests. The LLMs outperform models based on word and character frequencies, which themselves outdo the simplest models based on word or character counts. Interestingly, however, the character count appears to be a more reliable indicator than the word count.</div></div>","PeriodicalId":51794,"journal":{"name":"World Patent Information","volume":"79 ","pages":"Article 102321"},"PeriodicalIF":2.2,"publicationDate":"2024-11-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142652739","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Our findings indicate that while the number of publications in the literature on microalgae bioreactors has been increasing, the number of patent applications has decreased since 2015. Literature on microalgae bioreactors primarily focuses on the use of different bioreactors to cultivate microalgae, treat wastewater, and generate biofuel. Meanwhile, patented technology research is mainly concentrated on the study and transformation of microorganisms and their components. The overall trend in this field shows a decreasing coupling degree, suggesting that the field of microalgae bioreactors has reached a mature stage and is currently experiencing a bottleneck period. This article utilizes a combination of literature visualization and patent analysis to identify technological gaps within the field of microalgae bioreactors.
