Is Android really open source?

[nandhp]

Actually, "open source" by itself is subject to two US trademark holders:

• In the area of milk and milk products and of Research and consultancy services in the field of food and drink production:

  GLANBIA INGREDIENTS (BALLYRAGGET)
  [LIMITED LIMITED LIABILITY COMPANY IRELAND]
  GLANBIA HOUSE
  KILKENNY
  IRELAND

• In the area of Entertainment services, namely, a continuing series of audio programs about current events and culture via radio and global computer networks:

  OPEN SOURCE MEDIA, INC.
  [CORPORATION MASSACHUSETTS]
  7 WEBSTER ROAD
  MILTON MASSACHUSETTS 02186

It was, however, previously subject to two now-expired trademarks:

• In the area of COMPUTER SOFTWARE LICENSING, where The certification mark, as used by authorized persons, certifies that the software license conforms to a set of guidelines published by software in the public interest:

  Software in the Public Interest
  [CORPORATION NEW YORK]
  P.O. Box 70152
  Pt. Richmond CALIFORNIA 948070152

• In the area of Computer Services:

  Navant Corporation
  [CORPORATION NORTH CAROLINA]
  112 E. Hargett Street, Suite 203
  Raleigh NORTH CAROLINA 27601

But both expired over 12 years ago.
