LocalHero1953 Posted February 25, 2021 Share #21 Posted February 25, 2021 (edited) Advertisement (gone after registration) If these lenses were designed and patented by other brands, it would be strange if those others didn't actually make them - just Leica. Sony should be well capable of making the this 16-35 since they presumably own the Minolta-Konica patents - but their 16-35 design is quite different. And without more detail from the patent to show how much of it is specific optics (geometry, glass etc) and how much is opto-mechanics (AF, OIS etc), it is difficult to draw firm conclusions. Patents are murky things. Edit: I've seen the edits to the previous post - I agree the patent appears to cover optical design, but it is above my pay grade to understand how far this goes as a proportion of the overall design of a new lens.

Owning the rights to a design doesn’t mean: A company can make that design at a cost that its target customers will be willing to pay for it A company have the manufacturing know how to implement the design Often times a company will file a patent just to keep competitors from being able take advantage of a design, even if they themselves cannot make use of it. Patent claims are a bit like prospecting stakes. You put stakes down to keep your competitors out of a certain space. Whether you choose to mine the claim or not is a different issue. Sometimes you might make more money leasing (ie. licensing) the stake/claim to another party and have them do the hard work than doing it yourself and trying to sell the goods.
