Westminster, CA asked in Patents (Intellectual Property) for California

Q: Can I file for a patent on a product that is already made but doesn't currently have a patent?

For example, I currently sell a Spray Bottle, however, I didn't invent it. If there's no patent on the item, could I file for one? Or would I have to change something about it? If so, is there a way to something about the product to file my own patent for it?

A: Patents are intended in reward inventors. If you did not invent the product, you cannot patent it.

You may be able to patent an improvement to the product as long as whatever you do is not obvious to someone that designs spray bottles. But you would need to invent this or pay someone to do the inventing on your behalf. The actual inventors would listed as inventors but you could be the assignee that controls access to the patent rights.

Note -- that your new patent a modified spray bottle cannot stop people from selling the old spray bottle that is not patented.

A: Most likely not.

You are limited by how long it has been in the public.

Consult with an attorney.
