Yes it looks like Oregon Grape and you can make jams and jellies from them. They are not very tasty raw. You can follow a blue berry jam recipe using commercial pectin or here is a recipe for jelly.
Oregon Grape Jelly Select firm ripe Oregon grapes. Wash, leaving on stems. Place in large preserving kettle, covering with water. Boil 10 minutes, then mash and boil 5 minutes longer. Drain through jelly bag. Measure juice into large preserving kettle and boil 10 minutes. Add ¾ as much sugar as juice. Stir until sugar is dissolved. Boil rapidly until it sheets from a spoon. Remove from heat, skim at once, and pour into hot, sterilized jars.Leave ¼” headspace.Adjust lids and process 5 minutes in a boiling water canner.After processing, take canner off heat. Remove lid. Wait 5 minutes before removing jars.
