US Patent: 261,486

Pipe Wrench Patentee: John E. Sanders - Indianapolis IN Granted:1882-07-18

The focus of Sanders' patent is the flat oval shank with threads cut on the narrower curved edges, a movable jaw frame sliding on that shank, and the adjusting nut within that frame. The spring-loaded toothed jaw mounted on that frame is very like the jaw included in Ira Morse's April 21, 1868 patent (no. 77,076). Both of these patents are cited on pipe wrenches produced by R.R. Rouse of Indianapolis, IN. Rouse ads also related expired pat. no. 59,852 to the adjustable jaw for the combination nut and pipe wrench.

GB Patent: 304,502

Improvements in Grinding or Abrading Machines Patentee: Cincinnati Grinders, Inc. - Cincinnati, Hamilton County OH Granted:1929-01-24

Abstract: In a centreless grinding machine the work guide makes contact with the surface of the work along a helical or other inclined line so that the points of contact become progressively nearer the grinding wheel or vary progressively in some other manner as the work is traversed axially through the machine. The machine comprises a grinding wheel 5 rotated by a belt 8 and adjustable jockey pulleys 15 from a shaft 11 and a regulating wheel 19 also rotated from the shaft 11 through gearing 25, 28, flexible shaft 30 and skew gearing 32. The shaft 20 which carries the regulating wheel is supported on a pillar 22 adjustable vertically and angularly to incline the wheel and cause it to feed the work axially through the grinding throat. Two guides are provided for the work, the front one 38 serving merely to keep the work between the wheels whilst the rear one 40 maintains it in proper relation to the grinding wheel. The guides are adjustable to and from the work by hand-operated screws 42, 44 and are mounted on slides 37, 39 carried by a bracket 36 on a slide 33 which is vertically adjustable by a rack 34 thereon and a pinion operated through gearing from a hand wheel 35. 'The guide 40 has a workengaging surface which changes progressively from the tangent 46, Fig. 3, at the commencement of the grinding operation to the tangent 47 at the termination thereof, the former being inclined to a horizontal line preferably at an angle of 58¢ whilst the latter is inclined at 39¢ so that the point of contact with the work becomes progressively nearer to the grinding wheel 5. The line of centres of the grinding and regulating wheels may be horizontal instead of vertical as shown, in which case the second guide 38 is dispensed with.

USPTO announces recipients of the 2020 Patent Pro Bono Achievement Certificate

WASHINGTON – The United States Patent and Trademark Office (USPTO) today announced the recipients of the 2020 Patent Pro Bono Achievement Certificate, which recognizes individuals and law firms that assist financially under-resourced inventors and small businesses seeking patents. 

Established under the 2011 America Invents Act, the USPTO’s Patent Pro Bono Program is a nationwide network of independently operated regional programs that match volunteer practitioners with financially under-resourced inventors and small businesses for the purpose of securing patent protection. Each regional program provides services for residents of one or more states.

In 2020, the program shattered its previous volunteer participation record, as more than 100 patent practitioners and over 25 corporations and law firms reported 50 or more hours of patent pro bono service to a regional patent pro bono program. The recognized practitioners are listed on the Practitioner recognition page on the USPTO website. 

“I want to thank all of the recipients for their commitment to helping under-resourced inventors and small businesses in what was an especially challenging year for so many,” said Drew Hirshfeld, performing the functions and duties of the Under Secretary of Commerce for Intellectual Property and Director of the USPTO. "The work of these practitioners helped contribute to the 273 pro bono patent applications we received in 2020. Because of their service, the innovation economy is stronger.” 

To date, more than 1,800 patent practitioners have agreed to volunteer their time and resources to help make the Patent Pro Bono Program a success. Since 2015, these legal professionals have filed more than 1,500 patent applications on behalf of their pro bono clients.

For more information on participating, visit the Patent Pro Bono Program page and click on your state to identify a regional program in your area, or email

TTAB introduces additional programs for COVID-related applications

In response to the COVID-19 pandemic, and in view of the critical need to develop and help speed to market medical products and services to combat COVID-19, the United States Patent and Trademark Office (USPTO) initiated the COVID-19 Prioritized Trademark Examination Program in June of 2020.

To further support efforts to combat COVID-19, the USPTO is now initiating a Pilot Prioritized Review Program for Appeals Related to COVID-19, in which the Trademark Trial and Appeal Board (TTAB) will expedite the review and issuance of ex parte appeal decisions for applications examined under the COVID-19 Prioritized Trademark Examination Program.

To further support these efforts, the USPTO will initiate a Conference Pilot Program for Oppositions Against Applications Related to COVID-19. With this program, a TTAB attorney or judge may participate in the parties’ mandatory settlement and discovery planning conference, as is always available upon request of a party, if the involved application was examined under the COVID-19 Prioritized Trademark Examination Program. Such conferences can be useful to the parties to provide clarity and procedural information.

For additional information on these programs, see the USPTO’s notice on the topic or visit the TTAB webpage on the USPTO website.
