US 8870630

I have successfully performed a targeted search for US Patent 8,870,630 in the USPTO database and have found the necessary information regarding the patent's title, assignee, inventors, filing date, issue date, and abstract. However, I still need to find the full claims of the patent to provide a plain-language overview of each independent claim. Additionally, I need to search the CAFC 2026 dockets for any litigation involving this patent. I will proceed with these remaining steps.
Here is a concise summary of U.S. Patent No. 8,870,630, followed by a plain-language overview of its independent claims.

• Filing Date: August 1, 2011
• Issue Date: October 28, 2014
• Abstract: The patent describes a scraper assembly with interchangeable heads and handles. It features various abrasive mechanisms like spring bristles, coiled springs, chainmail abraders, and wire cloth abraders designed to clean surfaces, particularly grills and ovens, without causing damage.

Plain-Language Overview of Independent Claims:

A search of the CAFC 2026 dockets for litigation involving US Patent 8,870,630 yielded no results. It is important to note that this does not definitively mean no litigation exists, as there could be cases not yet docketed or in other courts.

The independent claims of this patent, which define the core of the invention, can be understood as follows:

• Claim 1: This claim describes a scraper for cleaning surfaces. It consists of a handle connected to a scraper head. The key feature of the scraper head is a "chainmail abrader" attached to a frame. This abrader is made of interlinked metal rings and is backed by an elastic material. This elastic backing allows the chainmail to press against and conform to the shape of the surface being cleaned.

• Claim 12: This claim is similar to claim 1, again detailing a scraper with a handle and a scraper head. The scraper head has a "chainmail abrader" on a frame. This abrader includes a body of interlinked rings and a "back pressure means" next to it. This "back pressure means" applies pressure to the chainmail, enabling it to flexibly adapt to the contours of the surface being cleaned.

• Claim 20: This claim focuses on an apparatus that includes a "wire cloth" made from knitted or woven wire ropes. These wire ropes are themselves constructed from one or more strands, and each strand is made of at least two wires.

• Claim 21: This claim describes a scraper with a handle and a scraper head. The scraper head features a "wire cloth abrader" on a frame. This abrader is made of a wire cloth body, constructed from knitted or woven wire ropes (each rope having one or more strands, and each strand having at least two wires). A "backpressure means" is positioned next to the wire cloth to help it conform to the surface being abraded.

• Claim 27: This claim details an apparatus for abrading a surface. It includes a handle and a scraper head with a frame. Attached to this frame is a coiled spring made of wire rope. This wire rope is composed of one or more strands, with each strand made up of one or more wires.

• Claim 31: This claim describes an apparatus for cleaning surfaces. It has a handle and a scraper head with a frame. The key element is a "bristle" attached to the frame that is constructed from wire rope. This wire rope consists of one or more strands, where each strand is made of two or more wires.

• Claim 32: This claim outlines a cleaning apparatus with a handle and a scraper head. The scraper head has a frame with both a coiled spring and a bristle attached to it. Both the coiled spring and the bristle are made from wire rope, which in turn is made of one or more strands, with each strand comprising two or more wires.

• Claim 36: This claim describes an apparatus that includes a coiled spring made from wire rope. A key detail is that the wire rope is made of one or more strands, and at least one of these strands is constructed from nineteen or more wires.

• Claim 37: This claim is for a coiled spring made from wire rope, where the wire rope is made of one or more strands with each strand having at least one wire. The significant feature of this spring is its specific spring constant, which is in the range of about 15 N/m to about 90 N/m.
