RE: Ligature Patents, Bonade

As you regularly tell us, Mark [re: copyrights], be cautious of FREE legal advice. Patents [both utility and design] are different and in my experience, complex. A bit of exploratory searching on the USPTO and/or IBM patent sites, I somewhat prefer http://patent.womplex.ibm.com/boolquery, will give a sense of history and some technical info. A simple search of Ligature-AND-Clarinet turned up 11 patents, US 2,791,929 to Bonade [1955, well expired!] cited as reference in 4,428,271 [Winslow, may not be expired!]. Adding -OR-Woodwind retrieved 113 pats, prob. many to saxes, and a comprehensive search of Class 084, Subclass 383R will prob. yield more! A copy of Bonade [and others] could be obtained from a US Patent Depository Library [each state has at least one], possibly by your local library reference-person. I would expect these pats will mention suitable materials of construction. If you wish a bit more info, just ask. Don
