Washington: IBM has reportedly accused Twitter of infringing upon at least three US patents, related to URLs.
The microblogging site, which is heading to its first public debut, has been accused of the uniform resource locators (URLs), which is a method for presenting advertising in an interactive service and programmatic discovery of common contacts.
According to Mashable, Twitter has said that based upon its preliminary review of the patents, it believes it has meritorious defenses to IBM's allegations.
However, Twitter has also added that there is no assurance if it will be successful in defending against IBM's allegations or reaching a business resolution that is satisfactory to them.
The report said that Twitter has just nine US patents compared to the 774 that Facebook had when it went public last year.
Twitter is set to go public with its IPO scheduled for either Nov. 6 or Nov. 7 and the company is said to have raised the price of its shares to 23-25 dollars, up from the previous 17-20 dollars, valuing the company at around 14 billion dollars.
