• Technical reliability based on heavy, continuous and international use
• Emphasis on the quality of our software engineering support

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 11th 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 RTPatch Server (previously called dfc-gorilla), a radically different approach to fast, resource-efficient byte-level differencing of files of any size. RTPatch Server'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. RTPatch Server technology is not subsumed in previous or other technologies, nor is it a replacement to existing Pocket Soft technologies. RTPatch Server enables byte-level differencing to be applied in ways that were previously impractical or not feasible.

2006
Pocket Soft is granted a patent for RTPatch Server (7,143,115).

2009
Pocket Soft created the first multi-core enabled byte-level differencing engine in version 5 of RTPatch Server.

2010
Pocket Soft opened a new multi-core programming tools product line. The first tool, UnThread™, is a general purpose multi-core programming SDK that was developed to speed time to market of RTPatch Server 5. UnThread is available from Postulate5, a division of Pocket Soft, Inc.
