Donald Weder (born 1947) of Highland, Illinois is an American inventor and businessman. Weder holds 984 utility patents and 413 design patents for a total of 1397 US patents. Weder is still actively inventing, so his ultimate number of patents is yet to be known.
Highland Supply Corporation
Since 1977, Donald Weder has been President of Highland Supply Corporation or "HSC". HSC was founded in 1937 by Donald Weder's father, Erwin Weder, to make corsage containers, and was substantially expanded by Donald Weder. HSC is now offering over 12,000 products for the floriculture industry. Highland Supply Corporation was recognized by Design for the Environment (United States Environmental Protection Agency partnership program)  for its commitment to environmental safety. Over the past three decades, Highland Supply claims to have planted well over 100,000 trees at various sites and preserved over 1000 acres of timberland.
Weder's patents are mostly related to the floristry industry, although in recent years as his sons Erwin and Andrew increasingly handle business affairs, Weder has turned to other technologies and industries, as well.
Weder's patents are owned by the Weder Family Trust, an offshore asset protection trust of which his sister Wanda Weder (who is also Senior Executive Vice President of Highland Supply Corporation) is trustee. This trust is administered by Southpac Trusts Limited.

Weder has been honored by civic, inventor and floral industry organizations for his philanthropy as well as his inventorship.
