Need trademark to appear only on the first instance in each topic

[Seema]

Hello,
We are using the trademarks setting to apply the trademark to our product name. We have a conref for the product name on which we have applied the trademark setting. Is there a setting which will allow us to display the trademark symbol only to the first occurrence of the product name in each topic in the documentation?
Thank you,
Seema

Hi Seema,
To what output format are you publishing? What version of Oxygen are you using? Are you using the publishing engine bundled with Oxygen or an external DITA OT publishing engine?
Can you give me an example of how your DITA XML content looks like when you use the product with the trademark symbol?
Regards,
Radu

Hi, we are currently publishing to pdf, but in future we'd also like to fix this for html. We're using <oXygen/> XML Author 25.0, build 2023013006. Currently we're using the publishing engine bundled with Oxygen to generate pdfs, but we'll likely switch to external DITA-OT builds in future.
This is how the tm looks in the DITA source:

Thank you.

Hi,

It seems that for the PDF output at least the trademark symbol is always output by default. Possibly a PDF XSLT customization could override a certain xsl:template to avoid outputting the trademark symbol for subsequent occurrences in the same topic but I do not have a clear solution for this:

Thank you Radu, we will look into customizing our pdf transform further.
