According to WWD, a trademark application filed with the U.S. Patent and Trademark Office on January 16 suggests the actress may be preparing to enter the skincare and cosmetics market under the SYRN name.
Trademark attorney Josh Gerben flagged the filing, which covers skincare products, beauty care preparations and cosmetics.
The application is listed as an 'intent-to-use,' meaning products could currently be in development, or that the brand is securing protection for future expansion.
No specific product names or formulations were detailed in the filing.
Sydney launched SYRN last week, positioning the label as a direct competitor to powerhouse brands like Kim Kardashian's Skims and Rihanna's Savage X Fenty.
The line offers 44 sizes, ranging from 30B to 42DDD, and is organized into four distinct 'modes': Comfy, Playful, Romantic and Seductress.
While recently speaking to Cosmopolitan, the actress said inclusivity and wearability were non-negotiable from the start.

'I'm always like, 'I want to see it on every body.' I can't be the only model. I need to make sure everyone feels really good in it. If I wouldn't wear it, I wouldn't want to make it.'
Sweeney echoed those sentiments in a recent interview with Elle, revealing she was motivated by a desire to create a brand that speaks to women rather than dictates to them.
'I wanted to create a world and a feeling,' she said. 'I wanted to build a lingerie brand that feels like it understands women instead of talking at them. SYRN is about confidence without pressure - feeling sexy, powerful, soft, playful, or all of the above, depending on the day.'
The actress, who is the sole founder of the brand, has been candid about her personal experiences with ill-fitting bras from a young age, noting that comfort was just as important as aesthetics when designing the line.
She left little to the imagination in the racy look
