  signals

15
Intellectual Property Agreements

• Purdue is sensitive to the confidentiality
  requirements of industry
• Non-disclosure agreements (already in effect with
  Parker)
• Confidential or delayed thesis options
• Delayed or generalized publication options
• Intellectual Property Ownership
• Purdue can license internally developed
  technologies in exclusive or non-exclusive
  agreements
• Trade Secrets (further research funded is
  expected)

16
Summary

• Purdue is well positioned with faculty, students,
  and laboratories to serve the future technology
  requirements of industry
• Funded graduate student research projects
• Undergraduate helpers for graduate students
• Developing the skilled employees for Parkers
  future
• Purdue has made a significant and long term
  commitment to the development of new and exciting
  technologies in fluid power
• Fluid power means new technologies at Purdue, not
  maintaining a mature technology
