1986
Pocket Soft was established as a privately-held corporation specializing in technical and systems software development. Early products include Pocket DOS, an operating system for handheld computers (the origin of the name Pocket Soft); .RTLink, a DOS extender; and VMData, a C compiler extender.
1991
Pocket Soft created the commercial byte-level differencing space with the release of RTPatch, now in its 10th major revision. RTPatch is the "gold standard" of software update systems, against which all others are measured. Literally tens-of-billions of RTPatches have been flawlessly distributed and applied by computer industry companies, other corporate users and government agencies. This heavy level of real world usage continues to increase, and assures the reliability, usability, and performance required for mission critical internet updates/upgrades of programs and data. RTPatch is Certified for National Defense use under Defense Priorities and
Allocations System Regulation 15
CFR Part 700.
1999
Pocket Soft is granted a patent (6,526,574) for the third complete rewrite of the byte-level differencing algorithm used in RTPatch.
2003
After over three years of research and development, Pocket Soft released dfc-gorilla, a radically different approach to fast, resource-efficient byte-level differencing of files of any size. dfc-gorilla's lossless compression is not content dependent, so it may be used wherever data is changed at one location and must be efficiently updated and/or stored at another. dfc-gorilla technology is not subsumed in previous or other technologies, nor is it a replacement to existing Pocket Soft technologies (e.g., RTPatch). dfc-gorilla enables byte-level differencing to be applied in ways that were previously impractical or not feasible.
2006
Pocket Soft is granted a patent for dfc-gorilla (7,143,115).
2007
Pocket Soft continues to innovate in the enterprise-level data transmission and data deduplication spaces. |
