... I'm curious if you know how this works for marketing inventions and gadgets for a hobby market? There seem to be quite a few very small businesses that appear to be successful in some niche of a niche market (I'm thinking of beer brewing, wine making, wood working, music, etc). Many of them seem to start small, get some exposure on the hobby forums, lots of word of mouth (post?), set up a web site, and off they go. It may or may not be enough for them to quit their day job, but I see them around for years and growing their product line, so it must be enough to be worthwhile.
Yes, absolutely. IMO the key is "niche." I have a friend who was gunsmith to the US Olympic team, basically working out of his house at the end of a Tennessee country road as a solo craftsman taking care of and engraving high end guns. He "opened up" on the internet and worked the high-end shooting community to the point where he now has a couple of employees. The joke is that his road had no name but as the business developed UPS contacted him and said that they would no longer deliver to a no-name road. So he had to go to the county board to get his road named!
I had a SCORE client, brilliant guy, who was selling rock 'n roll branded t-shirts on the internet, working out of his house. Long story short, it grew to the point that he rented some space, which he has expanded at least once, and has a couple of employees. His wife was happy when moved out because he had their bathroom closet full of shipping supplies.
... does it make sense that someone can start on a shoestring for something like this? I guess the internet kind of acts as the old craft or industry shows ...
Yes. I happens all the time, but a large fraction of the niche-y sites you see are labors of love rather than being economic successes. I had another client, a speech pathologist, who sold teaching tools like puzzles and music. She loved it but struggled to make money. As far as I know she is still struggling. Her big issue was that she couldn't achieve the scale needed to have her products manufactured cheaply in Asia, so her margins were thin and real volume was not attainable without a big $$ gamble on inventory.
... I understand that patents probably cost more than any benefit for something like this, but I suppose they still need a patent search to avoid getting a cease-desist from some other patent holder?
Without knowing the OP's idea it's hard to say for sure, but given his market I think getting a good patent would be difficult for anyone. By "good" I mean broad enough to stop similar and copy-cat products. A narrow patent is easy; I have three or four myself that megcorp paid for. They are pretty useless. Principally they are ammunition for the constant megacorp patent wars.
for designs on products I think you want a trademark. Patent is usually for a concept that does something - widgets and gadgets. I think some sort of design protection is mandatory before you engage the rest.
Nope. A trademark doesn't protect a design at all. It protects a name and, usually, some kind graphical representation. For example, the name "Target" for a retail store and the Target bullseye. Example: Kleenex. How many identical products are out there under other trade names?
Life is full of risks. On the subject of small and startup businesses I think that in most cases the expense and delay in getting to market are not worth it. They are nice things to give the lawyer when you also give him the $20K retainer check to do battle with a supposed infringer.
