Legal rights to sold presentations

[wiebesworks]

I while ago I sold a bunch of chess powerpoints to a school principal. I added a copyright mark to the slides to signal that they are for intended use only. 

This intended use was for the school to shoot chess videos for their school chess program, from the presentations and scripts I provided. We didn't specifically clarify beforehand what the full extent of the rights to the product was, but that intended use at least was clear.

Now I want to use the same slides, which I still consider my creative property, to make videos of my own, start a youtube channel or something. I feel like if i sell course materials i retain creative ownership. How does this work legally, in general and via Fiverr? The buyer stated he wouldn't like to see videos made by me using the same slides, since he wants to create videos with them himself for his schools chess players. It was clear that this internal use in his school was the purpose of the powerpoints and scripts i provided. 

 

What are your thoughts? Thanks in advance

This from the terms of service might be helpful in your case. Highlights are mine. 

"Ownership and limitations: When purchasing a Gig on Fiverr, unless clearly stated otherwise on the Seller's Gig page/description, when the work is delivered, and subject to payment, the Buyer is granted all intellectual property rights, including but not limited to, copyright in the work delivered from the Seller, and the Seller waives any and all moral rights therein. Accordingly, the Seller expressly assigns to the Buyer the copyright in the delivered work. All transfer and assignment of intellectual property to the Buyer shall be subject to full payment for the Gig, and the delivery may not be used if payment is cancelled for any reason. For removal of doubt, in custom created work (such as art work, design work, report generation etc.), the delivered work and its copyright shall be the exclusive property of the Buyer and, upon delivery, the Seller agrees that it thereby, pursuant to these Terms of Service, assigns all right, title and interest in and to the delivered work to the Buyer. Some Gigs (including for custom created work) charge additional payments (through Gig Extras) for a Commercial Use License. This means that if you purchase the Gig for personal use, you will own all rights you require for such use, and will not need the Commercial Use License. If you intend to use it for any charge or other consideration, or for any purpose that is directly or indirectly in connection with any business, or other undertaking intended for profit, you will need to buy the Commercial Use License through a Gig Extra and will have broader rights that cover your business use."
