Overview

Access Systems Americas, Inc., formerly known as PalmSource, is a software entity associated with the development and licensing of Palm OS and its successor initiatives. Its history began inside Palm Computing, where a dedicated subsidiary was established in January 2002 to handle the operating system business. The subsidiary was named PalmSource the following month and was later separated from Palm in October 2003, when PalmSource became an independent company while Palm itself adopted the palmOne name. The company's principal business was not the manufacture of handheld computers, but the creation, licensing, and support of software platforms for personal digital assistants and other embedded devices. Palm OS became one of the best-known operating systems in the early PDA market. According to the referenced Wikipedia material, devices using Palm OS had reached approximately 38 million units sold since 1996 by the mid-2000s. Licensees and device makers associated with the platform included Palm, Samsung, IBM, Aceeca, AlphaSmart, Fossil, Garmin, Group Sense PDA, Kyocera, PiTech, Sony, and Symbol. The ecosystem also included application distribution and software-development activity, with PalmSource-related channels and third-party catalogs offering thousands of programs. PalmSource attempted to develop a successor to the classic Palm OS. In January 2004 it announced Palm OS Cobalt, a newer generation intended to extend the platform beyond the original operating system architecture. Cobalt did not obtain sufficient support from hardware licensees, limiting its commercial impact. In December 2004, PalmSource acquired China MobileSoft, bringing in mobile Linux technology and leading the company to pursue a Linux-based direction. This work evolved into the Access Linux Platform, which was positioned as a successor platform rather than a simple continuation of the original Palm OS. The company also expanded beyond Palm-derived technology by acquiring BeOS from Be Inc. in August 2001. BeOS was a desktop operating system known for its multimedia and responsive system design. The acquisition gave PalmSource ownership of another operating-system technology base, although the referenced material does not establish a broad commercial revival of BeOS under PalmSource. PalmSource's corporate relationship with Palm remained significant after the spin-off. In 2003, PalmSource and palmOne established a holding company that controlled the Palm trademark. In May 2005, palmOne bought PalmSource's interest in that trademark for US$30 million, with transitional trademark rights granted to PalmSource and its licensees. In September 2005, ACCESS, a company known for mobile and embedded web technologies including the NetFront browser, acquired PalmSource for US$324 million. PalmSource announced in October 2006 that it would adopt the ACCESS name, aligning the business with its new parent. The later Access Systems Americas designation therefore reflects the continuation of this software and intellectual-property business under ACCESS rather than the independent PalmSource company of the early 2000s. Publicly available material in the supplied references provides limited information about the entity's later organizational structure, current products, headquarters, executives, and present operating status. It is best understood historically as a mobile operating-system and embedded-software business tied to the Palm OS ecosystem and subsequently incorporated into ACCESS's broader technology portfolio.

History

Access Systems Americas is rooted in Palm's decision to separate its operating-system activities from the broader handheld-computer business. Palm established a wholly owned subsidiary in January 2002 to develop and license Palm OS, naming it PalmSource in February. This structure allowed the software operation to pursue platform licensing and ecosystem development independently from Palm's hardware and consumer-device activities. PalmSource became an independent company in October 2003 when it was spun off from Palm. Palm adopted the palmOne name, while palmOne and PalmSource created a holding-company arrangement concerning the Palm trademark. PalmSource continued to develop the operating system used by a large installed base of PDAs and other devices. The supplied reference identifies a broad group of licensees and manufacturers, including Palm, Samsung, IBM, Sony, Garmin, Kyocera, Fossil, and Symbol. The platform was supported by a substantial application ecosystem distributed through software catalogs and download services. The company pursued a next-generation platform strategy during 2004. Palm OS Cobalt was announced in January as a successor to the classic Palm OS, but the initiative failed to gain enough support from hardware licensees. PalmSource then acquired China MobileSoft in December 2004. China MobileSoft's mobile Linux capabilities influenced PalmSource's subsequent decision to extend its operating-system work onto a Linux architecture, leading to the Access Linux Platform initiative. PalmSource's technology portfolio also included BeOS, acquired from Be Inc. in August 2001. This acquisition broadened its software assets beyond Palm OS, although the available reference does not provide evidence of a major BeOS product program under the later Access identity. The company's ownership and brand arrangements changed again in 2005. In May, palmOne bought PalmSource's share of the Palm trademark for US$30 million. PalmSource and its licensees received specified transitional rights for four years. Later in 2005, ACCESS acquired PalmSource for US$324 million. ACCESS was active in mobile and embedded web technologies, including its NetFront browser, and the acquisition placed PalmSource's operating-system assets within a broader mobile-software company. In October 2006, PalmSource announced that it would rename itself ACCESS. The Access Systems Americas designation represents the later corporate identity associated with this business in the United States. The supplied sources do not establish a complete account of subsequent corporate activity, current management, headquarters, or whether the named entity remains an independently operating brand. Its documented historical significance lies in Palm OS, the attempt to develop Palm OS Cobalt, the Linux-based successor direction, and the transfer of Palm's operating-system intellectual property into ACCESS.

Products and positioning

A mobile and embedded-software platform business focused on operating systems, licensing, and related developer ecosystems rather than consumer hardware manufacturing.

  • Mobile operating system · 1996

    Palm OS

    Palm OS was the company's principal mobile operating-system platform for personal digital assistants and related embedded devices. It was licensed to multiple hardware manufacturers and supported a substantial third-party application ecosystem. The reference associates the platform with approximately 38 million devices sold since 1996 by the mid-2000s, across manufacturers including Palm, Samsung, IBM, Sony, Garmin, Kyocera, Fossil, and Symbol.

  • Next-generation mobile operating system · 2004

    Palm OS Cobalt

    Palm OS Cobalt was announced in 2004 as a successor to the classic Palm OS. It represented PalmSource's attempt to modernize the platform and create a new generation for licensees. The initiative did not achieve sufficient hardware-licensee support and did not become a broadly adopted commercial successor.

  • Linux-based mobile operating system

    Access Linux Platform

    Access Linux Platform was the Linux-oriented successor direction pursued after PalmSource acquired China MobileSoft. Rather than continuing solely with the original Palm OS architecture, PalmSource sought to place Palm OS capabilities on a Linux foundation. The supplied material identifies the platform as a successor initiative but does not provide detailed release, adoption, or current-support information.

  • Desktop operating system

    BeOS

    BeOS was acquired from Be Inc. in August 2001. It was an additional operating-system asset in PalmSource's portfolio, separate from Palm OS. The available reference does not document a substantial new BeOS product line or a later commercial relaunch under Access Systems Americas.
