Split pivotDW-Link inventor David Weagle applied for patents on a concentric rear axle pivot rear suspension system called Split Pivot in 2006.[8] The Split Pivot design was awarded it's first patent in the USA on May 18, 2010, US Patent 7,717,212. The Split Pivot suspension is also described in patent applications in the USA (US2008/006772 A1 and US 2008/00738 A1) and Europe (WO2008/027277 A2).[9][10]

 

The Split Pivot System was designed to allow the separation of braking and acceleration forces in a bicycle suspension. As with Dave's dw-link design, the Split Pivot design has been licensed within the bicycle industry, with licensing companies releasing new models in 2010 and beyond. In June 2010, speculation that Cycles Devinci from QC, Canada would be a Split Pivot partner was confirmed on the cycling news site pinkbike.com.

After Mr. Weagle's patent applications were filed, Trek Bicycle Corporation released a version of the Split Pivot design called active braking pivot (ABP) in early 2007. In identical fashion to the Split Pivot design, the ABP system uses a rear pivot concentric to the rear axle. Trek's design allowed their new full suspension system to look very similar to previous models, but dramatically improved their ride quality. ABP reduces brake feedback that is typically felt by the rider as suspension stiffening. This allows the suspension to remain active while braking — hence the term, active braking pivot.

 

Split Pivot patent applications predate all patent applications filed by Trek. [9][10]

 

Trek also introduced a full floater system to go along with the ABP. The full floater system mounts the rear shock to two moving points in the suspension (rocker link and an extension of the chainstay). Other systems mount the shock to one end on the swing-arm, and the other to a fixed mount on the frame. This means as one part of the suspension compresses the shock, the other end of the shock moves as well. This allows Trek engineers more freedom to more accurately and precisely tune the system's leverage ratio. This functionality is also described in David Weagle's Split Pivot patent applications. [10]

split pivot vs. treks abp

1. A suspension system for a vehicle comprising a wheel link floating pivot, a wheel rotation axis, a wheel link, and a shock absorber, wherein said wheel link floating pivot is concentric with said wheel rotation axis.

1. A bicycle frame assembly comprising: a frame for supporting a rider; a swing arm having a first end pivotably connected to the frame and a second end for pivotably engaging a rear wheel assembly; a seat stay pivotably connected to the rear wheel assembly such that the seat stay and, the swing arm independently pivot about, and a rear wheel rotates about, a common axis; and a rocker arm attached to the frame and connected to an end of the seat stay opposite the common axis of rotation.

specialized horst link patent - scott genius USA

http://www.bikemag.com/blog/7-23-08-previewed-the-new-scott-genius/

The Genius is back. A patent dispute with Specialized had prevented Scott from selling its Genius bikes in the U.S. for years, but the company has completely redesigned the bike for 2009 and will soon offer six versions of this new 150-millimeter trail bike.

 

 

 

It’s an important step for the company. Until know, the company lacked a model for mountain biking’s hottest market–the 5 and 6-inch travel trail bike category. “We have arrived in the off-road market and are no longer going to be perceived as a strong road company, but rather a strong brand,” said Adrian Montgomery, Scott USA’s marketing director.

 

 

 

Scott unveiled the new bike in Idaho, offering the chance for a few rides on Sun Valley’s finest trails. The bikes immediately drew attention to their carbon frames and proprietary rear shock. But the Genius 30s on display had a slew of important changes and features worth taking a closer look at.

 

 

 

First, the pivot location of the bike has moved from the chainstay to the seatstay. That crucial detail freed Scott from any patent disputes with Specialized and allowed the company to bring the line back to the United States. (Scott has sold a line of Horst-link Genius bikes in Europe and elsewhere for years.)

nächstes jahr hat specialized kein patent mehr auf das horst link

Was hast du erwartet? Liest sich doch kein Mensch durch sowas.

Ich zumindest hab genau drauf geklickt - gesehen dass da unmengen an wirr zusammengewürfelten sachen stehen und war wieder weg. Ich denke so ist es eben vielen gegangen.
