Is "have been" without "*-ing" present perfect continuous?

The are many variations of this question but they don’t answer my example. I wrote somewhere that "XYZ companies have been the engines of American innovation". Someone retorted "Have been, not they are?".

But I was under the impression that to use have/has been in this sense implies that they still are xyz. But looking up "present perfect continuous" reveals that there needs to be a verb ending with ing.

So what tense am I using in the above example? am I wrong to believe that I’m implying these companies still are engines of blah blah blah?
