af: not too fast. Is the "overall appearance" or "look" of a functional thing (chair, jewelry box) even subject matter for a design patent?
If I understand your question correctly, I believe the answer is yes. You claim the overall ornamental appearance of a functional thing. Numerous examples out there all the way back to Gorham (the ornamental design of a fork), the Coca Cola bottle (D48,160 from 1915), a nail buffer (Egyptian Goddess v. Swisa) and the iPhone4 (D636,392).
My hypothetical adjustable beach chair has a distinctive ornamental webbing (not equally dimensioned strips at right angles but alternating wide and narrow strips criss-crossed at 45 degs to each other). I'm claiming an ornamental design for an adjustable beach chair. The position of the (adjustable) back of the chair is irrelevant. The webbing "looks" and remains the same. I might say Fig 1 depicts the ornamental design when the chair is in the upright position. Figure "x" depicts the ornamental design when the chair is in the reclining position. Aren't these just different "views". In a top-down view, you might not even know what position the chair-back was in. What ornamental features are apparent to the ordinary viewer in ALL positions? The criss-cross pattern.
I would agree with you if I were just claiming the webbing and disclaiming the other elements as part of the environment. But if you were claiming the appearance of the entire chair, my understanding is that all elements of the appearance that you do not disclaim are limitations on infringement.
Here is simple example to understand the lines along I am thinking. Take, for example, a vase with a unique shape. The vase also has a unique surface ornamentation. Do you file one design patent or two? Say that both the shape and the surface ornamentation are important to the client. I would file two. One for the vase disclaiming the surface ornamentation as part of the environment and a second one for the surface ornamentation showing the vase as the environment. If only the shape of the vase were important to the client, I would file a design patent with only the shape of the vase, possibly with the surface ornamentation shown as part of the environment.
I would not file a single design patent with both features together if I were trying to protect just the shape, otherwise someone could come along, make a vase with the same shape and no pattern and not infringe. Right?
I guess the point I am getting at is that my thinking is always that less is better (to the point of novelty and non-obviousness of course). If I claim a device that can settle basically into say three semi-permanent positions, each distinctly different looking (and each important to the client). Wouldn't I be better off with three design patents? Wouldn't incorporating all three into one design patent as different views allow someone to practice any one of the views without the other and not infringe?
Thanks for bearing with me on this.
