I have made a web machine out of HTML, CSS and JavaScript that, at a minimum, handles data otherwise handled in a spreadsheet application.
The machine's parts are essentially draggable holders (DIVs) and sortable lists (ULs) that are viewed in a three panel phone-sized display.
Hypertext and script modules control the action as well as record and store the results of dragging and sorting as machine-readable text files. (JSON)
Files are shared with other machines in collaborative work and used with selected apps for on line presentations and activities.
My question is, given Sir Tim Berners-Lee considered HTML too important to patent, if establishing the machine's patentability is sufficient to allow all to freely use it.
