Patent number: 7703810Abstract: A security device that increases the number of design options available for a machine testable security feature formed in part from a light absorbing (e.g., magnetic) material, while more effectively hiding or concealing this material, is provided. The inventive security device achieves these results by physically separating this security feature from a visually detectable or public security feature. Also provided by way of this invention is a process for preparing the inventive security device as well as a security document that employs one or more such devices.Type: GrantFiled: June 9, 2004Date of Patent: April 27, 2010Assignees: Crane & Co., Inc., Technical Graphics, Inc.Inventors: Paul F. Cote, Timothy T. Crane, Stephen B. Curdo, Gerald J. Gartner, Daniel G. Leeds

Patent number: 7243951Abstract: Durable security devices that are resistant to chemical attack and mechanical degradation and security articles employing such devices, are provided. By way of the durable security device of the present invention, opposing longitudinal borders adjacent an information-bearing layer are sealed, thereby preventing corrosive and/or degrading materials from reaching this layer through these sealed borders. In a preferred embodiment, at least a portion of the information-bearing layer is fully encapsulated, thereby rendering this portion or layer and the information conveyed thereby, impervious to chemical attack.Type: GrantFiled: August 19, 2003Date of Patent: July 17, 2007Assignee: Technical Graphics, Inc.Inventors: Paul F. Cote, Stephen B. Curdo, Gerald J. Gartner, Daniel G. Leeds, Brian C. Page, Gary R. Wolpert, Timothy T. Crane

Patent number: 6930606Abstract: A security device, such as a security thread, uses multiple security detection features provided by combining metal and metal/magnetic security features on a carrier substrate. The security detection features basically comprise an optionally repeating pattern of discrete metal/magnetic indicia and discrete metal or metal-dot formed indicia. The security detection features may also include at least one metal strip extending along the length of the carrier substrate and/or a plurality of metal dots located on metal-free portions of at least one surface of the substrate.Type: GrantFiled: June 15, 2001Date of Patent: August 16, 2005Assignees: Crane & Co., Inc., Technical Graphics Security Products, LLCInventors: Timothy T. Crane, Paul F. Cote, Stephen B. Curdo, Gerald J. Gartner, Gary R. Wolpert

Patent number: 6805926Abstract: A security label having one or more security elements is used on or in association with items, such as consumer products, that have value and are susceptible to counterfeiting. The security label is preferably used as a primary label directly affixed to the item or product. The security element(s) can be affixed to an outer or inner label surface, embedded within the label film or paper layer and/or laminated between two or more layers. One type of security element includes a security thread having indicia formed thereon that are not easily reproduced or duplicated. Another type of security element includes a machine-readable security element that provides encoded machine-readable verification data.Type: GrantFiled: February 22, 2002Date of Patent: October 19, 2004Assignee: Technical Graphics Security Products, LLCInventors: Paul F. Cote, Stephen B. Curdo, Gerald J. Gartner, Gary R. Wolpert

Patent number: 6549131Abstract: A method of covering, embedding or burying magnetically encodable regions, invisible to the naked eye at least on one side, in a magnetic/metallic security device begins by providing a security device carrier substrate having an imaged metallic region. A foil film is provided on a release coated carrier film. One or more magnetic regions are provided on either the foil film layer or the carrier substrate. Patterned, flat, or roller heated dies are used to contact and bond the foil film to the security device carrier substrate in at least those regions of the magnetic regions thereby producing a security device having covered, embedded or camouflaged magnetically encodable regions.Type: GrantFiled: October 6, 2000Date of Patent: April 15, 2003Assignees: Crane & Co., Inc., Technical Graphics Security Products, LLCInventors: Paul F. Cote, Gerald J. Gartner, Stephen B. Curdo, Daniel J. Leeds, Gary R. Wolpert, Timothy T. Crane

Patent number: 6255948Abstract: A security device having multiple security features is used with an item, such as a secure document, ticket, label or tag, to authenticate the item and/or encode data pertaining to the item. One example of the security device includes a carrier substrate, a metallic layer disposed on the carrier substrate, and a magnetic layer disposed on the metallic layer in substantial registration with at least a portion of the metallic layer, thereby providing both metallic security features and magnetic security features. The metallic layer and the magnetic layer also form graphic or visually identifiable indicia on the carrier substrate to provide a visual security feature. According to one method, the metallic layer is applied to the carrier substrate, the magnetic layer is applied to the metallic layer, and the layers are etched to form the graphic indicia. The magnetic layer can, in one embodiment, include a magnetic chemical resist that is printed on the metallic layer in the form of the graphic indicia.Type: GrantFiled: December 1, 1998Date of Patent: July 3, 2001Assignee: Technical Graphics Security Products, LLCInventors: Gary R. Wolpert, Gerald J. Gartner, Stephen B. Curdo, Paul F. Cote
