> There would need to be (1) an existing valid contract,

Your (1) is false. You can damage a business relationship that doesn’t involve a signed contract.

“Tortious interference with business relationships occurs where the tortfeasor intentionally acts to prevent someone from successfully establishing or maintaining business relationships with others.” https://en.wikipedia.org/wiki/Tortious_interference

They aren't doing it with the intent to damage his business. They're just doing something they would have done anyway.

You can't claim tortious interference just because someone throws a wrench in your business plans. Sanborn has about as much of a case as Microsoft has against Linus Torvalds for creating Linux and hurting their sales of Windows. (I'll give you this one for free: none.)

That’s arguable. They sent him an email concerned about the harm of disclosure with the upcoming auction. They then apparently got offended by the offer of money to sign an NDA which calls their future motives into question as they now had a beef with the guy.

Saying the actions themselves were not improper is also a defense, and could be perfectly viable even if they had beef with the guy.

"To be improper, interference must be wrongful by some measure beyond the fact of the interference itself, such as a statute, regulation, recognized rule of common law, or an established standard of trade or profession."

They don't need a defense: nobody has yet stated a claim!

It was claimed they committed copyright infringement and they admit to photographing his works as part of this discovery.

It actually being copyright infringement is questionable, but if so it would be improper behavior.

NAL but in copyright it’s not making a copy that’s problematic, it’s making that copy available to others. Anyone can take a picture of Mickey Mouse; one only has a problem when they start to sell it.

This cryptography solution is more akin to mathematics. And mathematics isn’t covered by the copyright law.

Civil penalties can be imposed when make a single copy without a fair use exception, this is why pre BitTorrent people got into trouble for downloading music for themselves. The government doesn’t care unless you get sued but they will enforce the lawsuit if you lose.

Criminal investigation and penalties occur with wide scale commercial distribution of copyrighted works.

They copped the actual message in its entirety not just a cryptographic formula. Further, his hand written notes may have creative expression even if the process itself isn’t protected by copyright. Similar to how software code is protected.

[tptacek]

Yep! That'd be a real claim. I hadn't seen that earlier.

That's not a tort in American law. In this country contractual arrangement is required for tortious interference.

[Retric]

There was a contract between the auction house and the artist.

However that’s not strictly required: “Wrongful interference in a business relationship occurs when there is no contract. The defendant attempts to disrupt the relationship, causing economic harm. If the defendant defames the business owner’s product, resulting in loss of business, that is tortious interference in the business.”

Your cite is about interference of contract... interference of business relationship is not an American tort.

[tptacek]

OK, but the interference still needs to be improper!

[Retric]

Agreed, though I’m not sure if it would be considered proper or improper here.
