• Inventor: Wilhelm A. Keller
• Original assignee: Medix Systems AG
• Application number: US 13/500,363
• Filing date: 2010-06-29
• Priority date: 2009-10-06 (flagged in the source as an assumption)

Purpose. The excerpt states that the invention "relates to a discharge arrangement comprising a cartridge or syringe for at least two components and comprising an accessory part, with one connecting component of a connecting device being arranged on the syringe or cartridge and another on the accessory part." In plain terms, it concerns the joint that links a multi-component cartridge or syringe to an attachment such as a mixer or closure cap.

Plain-language scope (limited to the excerpt). The supplied text does not include the claims or the detailed description, so the actual scope must be taken from the claims at the source. In the background discussion provided, the patent frames a bayonet-style connecting device (citing U.S. Pat. No. 5,033,650 A1), and notes earlier designs using differently sized outlets and corresponding inlets, a threaded cartridge with a union nut, coding ridges and indents for fit prevention, and a closure cap with stoppers. The excerpt does not describe the applicant's specific improvement beyond indicating that connection between cartridge and accessory is the subject matter.

What the excerpt does not establish.

• The language or number of the claims, and therefore the precise scope and any limitations. The classification listing (e.g., B05C17/00509, bayonet-type outlet connections) describes classification, not claim scope.
• The specific components of the connecting device as claimed, or how they differ from the cited prior art.
• Whether any statements in the background were adopted or distinguished during prosecution.
• Bibliographic details beyond those listed: the excerpt notes assignee "Medix Systems AG," lists later assignees, and shows a "2030-10-14" adjusted expiration and litigation/PTAB entries, but the operating rules exclude research into ownership transfers or litigation. These entries are not evaluated here and are recorded only as they appear in the source.
