NEEDHAM, MA. – January 16, 2007 -PTC (Nasdaq: PMTC), the Product Development Company?, today announced that Acorn Product Development, an innovative engineering outsource design firm developing products for consumer, computer, communication and medical companies, has begun an enterprise-level upgrade to PTC Windchill? PDMLink? to support its global product initiatives and sustain its current rapid growth.

Unlike many traditional design companies, Acorn offers its clients an optimized range of product development services from architectural analysis through manufacturing floor support worldwide. Recent Acorn projects include new product releases for Logitech, Network Appliance, Siemens and Sun designed using Pro/ENGINEER?. With development locations in Silicon Valley, Boston and China, Acorn has adopted a global product development strategy, successfully executing complex projects with geographically dispersed teams of engineers.?

To support this strategy, the company needed an enterprise product lifecycle management solution that would enable it to increase the efficiency of its processes for getting new products to market. An established user of Pro/ENGINEER with over 60 licenses of various PTC products, Acorn chose to expand its PTC technology investment to include Windchill for content and process management. Windchill will enable Acorn to manage data across a distributed product development environment with advanced controls for data that can be accessed by multiple entities inside and outside the company. The Acorn implementation was driven by NxRev, a leading PTC channel partner.

“The Combination of PTC technology with the experience of our value added reseller NxRev provided the most compelling solution to help us implement a global product development strategy in order to sustain and increase our competitive advantage,” said Ken Haven, chief executive officer, Acorn Product Development. “The single integral technology architecture of PTC’s Product Development System was the key differentiator for us because it simplifies product development while also providing the power and scalability to support our continued growth.? As we open new geographies, we feel confident that the remote staff, using Windchill, can immediately participate and contribute to product development.”

“Acorn is representative of many small and medium businesses that are leveraging PTC solutions to enable them to successfully compete with larger companies,” said Joshua Fredberg, vice president, product and market strategy, PTC. “We are very pleased that Acorn has chosen our integral solutions to help them optimize their product development processes and welcome the opportunity to help them achieve their business goals.”
