FOOTNOTES aBecause this table is limited to designs that could be patented, it does not include branded versions of the traditional 57/58-facet round brilliant. Cuts added since Overton (2004) are in blue type. bYears given are the issue date of the patent. A plus sign (+) means the author believes the cut is patented, based on reference(s) listed but could not confirm that fact by searching U.S. patent records (some of these are likely patent pending but as yet unpublished). A blank line means the author believes the cut is not patented based on reference(s) listed, but could not confirm that fact through other research. “Pending” means that the manufacturer has confirmed that an application has been filed. Patent data are as of April 2004. See References for specific patent numbers. cTrademark registration data as of April 2004. “Yes” entries include active applications in addition to registrations, and also include registrations in countries that are members of the Madrid Protocol, as these registrations are effective in the U.S. Entries marked “no” include expired, cancelled, and abandoned marks in addition to marks never registered. Note well that mere absence or abandonment of registration does not affect the ownership or validity of the trademark itself. dFull references are listed below. eThe design is protected by a registration with the U.S. Copyright Office. fAlthough the listed references identify J. Korn & Partners of Antwerp as the owner of the cut, the manufacturer reports that this is no longer the case (J. Korn, pers. comm., 2003). gPatented in Israel, 2002. hThe term is a registered trademark in Israel, which is not yet a member of the Madrid Protocol. iThis patent was held unenforceable in mid-2003 and is currently the subject of ongoing litigation (Gomelsky, 2003). jThe design is protected in the EC by registration with the OHIM. kDate of the design patent; a utility patent application is also pending, see Yaskil and Gertzman, 2003. lThe term is registered by QVC, not Diamonds 4 U; USPTO records contain an abandoned application for “Genesis 4 U.” mManufacturer claims a registration, but USPTO records show the application as abandoned. nPatented in Canada, 1986. oThe term is registered by Henry Meyer & Co as part of a logo but not for a . pManufacturer claims a registration, but no records were returned from USPTO or WIPO databases.
