i think you need to stipulate how you wish to analyze patents - the methodology or coding you wish to use. then you can look at software that implement it

You may want to customize this software, and others linked here:

Most patents do not resolve technical or system contradictions as defined by Altshuller. For the few that do, if you want to classify them in the fashion of Altshuller's technical contradiction matrix, then you will need to develop sophisticated natural language processing tools yourself. Look up natural language processing in python (e.g., http://www.nltk.org/book/) to start.

Remember, generic natural language processing is not possible because the possibilities explode with even small sentences and the problem becomes potentially incomputable (like a Busy Beaver problem).

Dear Kartik. Thank you for your reply. I am more interested in visualizing the evolution trend of a product. I would like to see the trend how the product evolve since the first invention of it. I am analyzing about the evolution trend of the zipper's design and development. I did it manually last month,reading and analyze about 940 patents. I try to contact WIPS, asking for the quotation of their software, but they didn't reply. That's why I am looking for an opensource software or any other suiatble software with reasonable price. Thank you.

Patents will not give you the actual trend of evolution of products, as most ideas do not gain market entry or dominance. Many patents today exist purely for blocking purposes. You can get better results by searching for patents or publications or specifications of products or services you can determine from evolutionary trajectories of current and past products. These evolutionary steps can be deduced through the 'laws' of system evolution (shortening of energy paths, more controllable fields, and so forth) from specifications of products of the present and past performing the same function.

Patenting is only valuable in stagnant industries that tend to be heavily regulated, which is most every industry at this time. See https://spectrum.ieee.org/tech-history/dawn-of-electronics/the-miraculous-1880s and https://spectrum.ieee.org/energy/renewables/moores-curse. Fast moving industries generally follow the rule of secrecy and first to market--see the book Against Intellectual Monopoly for further understanding: http://levine.sscnet.ucla.edu/general/intellectual/against.htm.

@kartik I agree with you. Since I am working on with designing an automatized zipper, it is quite hard for me to find pubilcation (journal or paper) writing about the zipper. That is why I moved to study about the patents related to the zipper. Thanks a lot for your feedback. Really appreciate it =)

Dear Mr. Baharom,

have a look at

http://aulive.com/

they might offer exactly what you are looking for. Get in touch with them for further support/information and say "Hi from Claudia from Berlin" in case you are talking to Simon Dewulf. Regards, Claudia Hentschel

Many thanks Claudia! =)
