A sampling of the cases that John R. Crossan has litigated in each of the IP subject areas, with indications of their technical or business subject matter, is provided through the links here and below for patents, trademarks, copyrights, unfair competition, trade secrets, and related anti-trust areas.

When John R. Crossan started into the IP law practice in 1973 - then called Patent, Trademark, and Copyright law - most all attorneys had full-service IP practices. Each attorney then came to know the intricacies of all forms of the intellectual property practice - not as today where big-firms' attorneys' practices often are very narrowly confined and even simple but comprehensive advice must be gleaned from multiple counsel. John R. Crossan enjoys litigating and trying important patent, trademark, and unfair competition cases to final result or settlement and through appeal and certiorari petitions where warranted. John R. Crossan also prepares, files and prosecutes to issuance applications for patent and trademark, and he negotiates licenses for companies and individuals. John R. Crossan also gives copyright, trade secret, and antitrust advices to clients.

John R. Crossan started his IP Law practice at THE HILL FIRM in Chicago, first reviewing Patent Office actions for preparing amendments and soon after writing original applications. He got a good start into IP litigation, also. For instance, his senior partner sent him to Washington to do an invalidity search at the Patent Office, expecting John R. Crossan to spend a week there. However, John R. Crossan found knock-out art in the first hour and so returned to Chicago the same day - saving the small business client four days of fees. His partner and he won the trial, at Shreveport, LA, using the art that John R. Crossan had found together with supporting testimony of the local inventor.

John R. Crossan was recruited to the boutique firm of COOK WETZEL AND EGAN at the start of 1978. There he promptly helped to try and win jury verdicts against IBM while representing a Seattle manufacturing firm, enforcing a patent on a mechanism for a collator for copy machines. His partner and he won a $7.5 million jury verdict for just the first few years of production and leasing of IBM's Series III copiers. John R. Crossan largely wrote the appellee briefs to have the judgment upheld on appeal. More cases and trials ensued, including a case wherein John R. Crossan defended Ford Motor Company from a contingency-case patent infringement claim. John R. Crossan litigated and tried another automotive product patent to a jury in Detroit in 1988.

The Willian Brinks firm (now BRINKS HOFER GILSON & LIONE) welcomed John R. Crossan at the start of 1989 to continue his litigation practice in the IP Law area. John R. Crossan litigated several patent infringement cases for Kimberly Clark and advised other Fortune 25 companies on patent and other issues, supervised patent application work for a major cell phone company, and counseled an agricultural equipment company on novelty and infringement issues. John R. Crossan also took on a contingency fee case for the law firm and a retired engineer in Toledo, Ohio, who alleged that he had been financially defrauded by his lawyer in a software development business venture. Starting with a copyright infringement claim, John R. Crossan and his team litigated and tried the case to a jury on misappropriation of corporate opportunity and attorney malpractice grounds. John R. Crossan's client there won a $22 million verdict.

Seeing much important IP litigation work go to general practice firms with IP sections, at the start of 1998 John R. Crossan joined CHAPMAN AND CUTLER, LLP, a national firm specializing in financial services law. In July 1998 the Federal Circuit Court of Appeals held that business methods should be patentable like any other methods (computer methods had been patented and upheld since the 1983 trials in Merrill Lynch's Cash Management Account cases). John R. Crossan then promptly filed for and obtained what seems to be just the second-issued pure business method patent, no. 6,338,040, for a method of preserving usefulness of gene-modification technology as against development of resistance in targeted bugs. Financial business methods never caught on, except in the federal tax area, and in October 2008 the Federal Circuit court has reversed itself and now requires a method either to use a specific machine or to transform an article, machine, or composition of matter. The Supreme Court has now cast some doubt on availability of “pure” business method patents, calling for further development of the law by the Federal Circuit Court of Appeals. Also, “tax avoidance” methods (whatever those may be) are made unpatentable by the 2011 America Invents Act. John R. Crossan continued his IP litigation practice at Chapman, representing banks, importers, domestic manufacturers, and others in patent and trademark cases across the nation and internationally, including in recapturing several domain names from cybersquatters through federal court injunction proceedings and in ICANN binding arbitration cases.

John R. Crossan has now opened his own boutique IP Law practice, starting in April 2009. John R. Crossan's Law Office is located on the 26th floor of the 875 North Michigan Avenue building, on Chicago’s Magnificant Mile, a popular shopping and business area. He is continuing his successful IP Law practice there and invites current, returning, and prospective clients to call or write to discuss their Intellectual Property creation, protection, and exploitation needs. John R. Crossan's goal is to work with clients to achieve excellent results in their businesses and competitive positions.
