B.thuringiensis toxins are highly species specific which provide economic, environmental benefits, potential for future control and spread of the technology worldwide. This makes the B. thuringiensis crystal proteins an interesting tool for the implementation in integrated pest management programs. It has gained importance over the last 100 years for its biocontrol properties which is used in this review as a case study and analysis of the patents granted on B. thuringiensis was carried out. This study categorizes a number of patents related to B.thuringiensis insecticidal crystal proteins, application of B.thuringiensis insecticidal crystal proteins and the development of patentable technologies. The analyses were done using various criteria like patenting trends over the years, assignees playing a major role, comparison of the technology used in different patents and the patenting activity across the insect orders. Patent documents related to bacterium B.thuringiensis contain a trove of technical and commercial information and thus, patent analysis is considered as a useful tool for R management and techno economical development. Patent analysis also helps identifying and evaluating new and alternate technologies, keeping abreast with latest technologies for business interests, finding solutions to technical problems and ideas for new innovative trends.</p>","PeriodicalId":74646,"journal":{"name":"Recent patents on DNA & gene sequences","volume":"6 1","pages":"64-71"},"PeriodicalIF":0.0,"publicationDate":"2012-04-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.2174/187221512799303181","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"30381743","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}

Pathologists are being confronted with increasing demands, from both clinicians and patients, to provide immunophenotypic and gene expression data from FFPE tissues to allow the planning of personalized therapeutic regimens. Recent improvements in the protocols for pre-analysis processing of pathological tissues aim to better preserve cellular details and to conserve antigens and nucleic acid sequences. These developments have been recently patented. The international protocol for the transporting of surgical specimens from the surgical theatre to the pathology department is to immerse the specimen in formalin. The alternative method of sealing the specimens into bags under a vacuum and then cooling is a well-accepted and environmentally safe procedure that overcomes the many drawbacks linked to transfer in formalin. Importantly, RNA is notoriously poorly preserved in FFPE tissue. Due to this, successful procedures for the extraction of genetic information from archival tissues have been the object of several studies and patents. Novel molecular approaches for RT-qPCR and gene array analysis on FFPE tissues are presented here.
